Introduction

Welcome to the CML Product Catalogue. The Catalogue is a new style composite publication that brings together the former CML Product Selector and the CML Communications IC Selection Guide. This document supersedes both of those publications in their entirety. The advantage of having the two publications integrated as one is that it allows you to browse through CML’s product families at an introductory level, and to then explore individual products in more depth - all within the same document. Within the first part (Product Overviews) the descriptions at the start of each section summarise product families. Tables are included that offer a comparison within groups of devices with key performance figures and product benefits. Following the links in the tables will navigate you to more detailed information on individual devices in the relevant sections of the second part (Product Descriptions). CML’s products are listed in numerical sequence overleaf, followed by tables that allow you to search for suitable devices by application or function.

Digital PMR/LMR and Analogue Two-way Radio Products High performance digital radio systems are migrating towards the Software Defined Radio model, where a common hardware platform can be used across a number of radio systems. System-specific operation and functions are fully software based within the DSP/microcontroller. The world of the DSP and the microcontroller is a digital one, yet the real world, including RF, is analogue. Therefore, the important functions sitting in front of the DSP are the analogue to digital converters and other auxiliary functions allowing the analogue world to interact with the digital one. The CMX983 AFE for Digital Radio bridges this gap between the DSP a digital radio’s RF section. Being flexible and high performance, this device can form the basis of a digital radio platform. It provides direct connection to and support of the RF section along with a host of auxiliary functions, effectively reducing the overall system size, cost and power consumption. The CMX983 is suitable for radio systems employing modulation bandwidths up to 25.8kHz and is usable in satellite communication, high performance wireless data and professional two-way radio systems.

The CMX983 provides a versatile interface to support a variety of transceiver architectures. The flexible nature of the main signal ADCs and DACs makes the device suitable for a wide range of narrowband radio systems, supporting modulation bandwidths from 6 up to 25.8kHz. Integrated auxiliary functions reduce PCB area with an ADC handling measurement of PA power and temperature, RSSI, battery and other parameters whilst controlling trimming of TCXOs and other functions via low power DACs. When coupled with other CML RF devices a highly integrated radio solution is possible, capable of supporting linear and constant envelope modulations. All devices are compatible with a 3.3V digital I/O and are supported by a common C-BUS serial control channel simplifying radio design.

The CMX994/CMX994A/CMX994E is a family of direct conversion receiver ICs with PowerTrade™, the ability to dynamically select power vs. performance modes to optimise operating trade-offs. Direct conversion receiver family with PowerTrade™ flexible power vs. performance modes CMX994 - Standard and low power modes CMX994A - Standard and additional low power modes CMX994E - Enhanced, standard and low power modes All three devices include a broadband LNA with gain control followed by a high dynamic range, very high IIP2, I/Q demodulator. The receiver baseband section includes amplifiers and precise, configurable bandwidth, baseband filter stages. LO generation is provided by an integer-N PLL and a VCO negative resistance amplifier; an external LO may also be used. LO dividers are provided for flexible multi-band operation. The devices operate from a single 3.3V supply over a temperature range of –40°C to +85°C and are available in a small 40-pin VQFN (Q4) package. The CMX994A enables a significant reduction in power by allowing LO phase correction to be turned off. A further reduction is made possible by the facility to disable either the I or Q channel. The CMX994E expands on that by adding an enhanced performance mode that features improved intermodulation in the receive path mixers. Operate from a single 3.3V supply over a temperature range of –40°C to +85°C and are available in a small 40-pin VQFN (Q4) package.

Digital PMR/LMR and Analogue Two-way Radio Products CMX264 Frequency Domain Split-band Scrambler Versatile Split-band Inversion Scrambling The CMX264 is a frequency domain voice scrambler for use in analogue cellular phone systems, fixed and rolling code voice scrambler applications.

Features  Full Duplex Operation

     

High Recovered Audio Quality

It contains separate Tx and Rx paths for full duplex operation and operates under µProcessor control via a simple serial interface.

Uses Split-Band Inversion Fixed or Rolling Code Capabilities

In the Tx path, scrambling is achieved by splitting the audio band into two parts, or subbands, and frequency inverting each one.

Simple Serial Interface Low Power Requirement with Standby Mode Supply Requirement Range: 2.7 to 3.3 V

The frequency at which the signal is split, the "split-point", can be either fixed or rolling between four possible settings resulting in a transmitted audio signal which is unintelligible to eavesdroppers.

Applications  Mobile Radio

Descrambling is achieved by a receive device set to the same split point as the remote transmitter.

 Fixed Code Voice Scramblers  Rolling Code Voice Scramblers

Thus if the Tx and Rx devices are synchronously cycled through the same sequence of split points, a clear recovered signal will emerge at the output of the receiver A 4.433619MHz crystal is used allowing up to four split points to be programmed. The device is designed to be compatible with existing mobile and cell phone circuitry.

The CMX7031 and CMX7041 are half-duplex processor IC platforms built on FirmASIC® technology that are suitable for use in multi-standard analogue Two-way Radio (TWR) systems. FirmASIC® component technology allows on-chip sub-systems to be reconfigured by a Function ImageTM (FI): this is a data file that is uploaded during device initialisation that defines the device's function and feature set. The CMX7031/CMX7041 enable a revolutionary new platform approach to radio design, enabling multi-mode analogue two-way radios to be developed based on a single radio platform, conforming to many systems: PMR, LMR, Trunking, Marine, Aviation, Amateur radio, NOAA weather radio and packet data radio. To enable full control of the radio functions and minimise the overall chip count, two user programmable system clock outputs are provides along with auxiliary ADC and DAC blocks. A user-programmable PLL, driven from the Xtal/reference clock input, generates all internal clocks and allows one clock source to be internally reused for both baseband and RF synthesiser functions (for CMX7031 only). A flexible power control facility allows the device to maximise powersaving whilst not processing signals or when specific functions are not enabled. New Enhancements:  Marine DSC Expansion Sequences, enables precise position using marine DSC

Applications

     

FirmASIC® component technology allows on-chip sub-systems to be reconfigured by a Function Image™ (FI): this is a data file that is uploaded during device initialisation that defines the device's function and feature set.

A number of the Function Images now support direct connection to CML’s CMX994 Direct Conversion Receiver. The combination of the CMX7131/7141 and CMX994 enables the highest integration, multi-standard FDMA digital/analogue PMR radio, to be realised. The CMX7131/7141 and CMX994 together address the market requirements for: Low power operation, small size, low cost, flexibility and high performance. Vocoder Support A number of Function Images manage voice and data systems autonomously with the CMX618 RALCWI (Robust Advanced Low Complexity Waveform Interpolation) Vocoder and third-party Vocoders. This minimises host microcontroller interactions enabling the lowest overall operating power and therefore the longest battery life for a digital PMR radio. Third–party Vocoders are also supported in a data transport mode of operation.

Digital PMR/LMR and Analogue Two-way Radio Products CMX823 Programmable Paging-Tone Decoder Multi-standard Tone Decoding for Analogue Paging The CMX823 is a high performance, low power, audio tone decoder that can operate on low S/N signals.

Features  Decodes 32 User-Programmed Tones

 Stores Two Lists of 32 Tones to Fast 

Each decoded tone frequency is user-defined to provide the flexibility to operate in a variety of paging, two-way radio and proprietary systems.

Switch Between Tone Sets Configurable Decode Response-Time and Decode Bandwidths Low Power: 0.75mA at 2.7V and 'ZeroPower' Powersave Mode Superior Signal-to-Noise Performance

Example systems and tones include: Motorola Quick Call series; GE groups A, B and Zetron, Reach and Plectron 2-tone radio paging; Motorola 5/6-tone paging; and the EIA, CCIR, ZVEI1 and EEA tonesets used for HSC radio paging and selcall.

  Low-Cost 3.58MHz Xtal/Clock  Supply Requirement Range: 2.7 to 5.5V

Up to 32 user-defined decode tone frequencies from 280Hz to 3500Hz are written to an internal RAM-based FIFO. (Two separate 32-tone FIFOs are provided and support fast switching between tone sets).

Applications  Two-Tone, 5/6 Tone and Voice Pagers

Each programmed tone (entry in the list) is user-assigned to one of two (or both) tone groups. Two-tone sequence decoding is simplified by dynamically enabling one or the other tone group via a mode selection.

    

Selective Calling (Selcall) Systems

The CMX823 asserts an interrupt on tone decoding state transitions, e.g. notone to decoded tone, decoded tone to notone, etc. STATUS and DECODED TONE PARAMETERS Registers may then be read and indicate the decoder status, the target tone decoded and its tone group.

CMX882 is a full-function half-duplex audio and signalling processor IC for FRS and PMR446 type facilities -for both complex and simple end-designs. Under the control of the host µC, all voiceband requirements are catered for: Voiceband and sub-audio filtering, pre/de-emphasis, compression and expansion, and audio routing and global level-setting with single or twopoint modulation in the transmit path. The combination of new and standard signalling functions of this product offer, under software control, increased functionality, versatility and privacy. Standard Extended-Code CTCSS and DCS is integrated with the new XTCSS code implementation. XTCSS provides better squelchcentred privacy codes with the added advantage of ‘silent operation': no annoying interference from other sub-audio users. XTCSS fitted radios enjoy more privacy and flexibility of operation. The CTCSS configuration of this product enables ‘Tone Cloning’. Additionally two unique features of this product are its CTCSS ‘All Call Code’ and ‘All Codes Monitor’ modes. XTCSS Signalling - A state-of-the art (squelch) signalling format, employing both sub-audio (CTCSS) and in-band (XTC) signalling concurrently, which offers more than twice as many privacy codes as standard CTCSS operation and completely eliminates interference caused by other traffic on the channel (quiet operation). Additionally the XTCSS signalling can be employed as on over-air control for such features as voice-scrambling and voicecompression. XTCSS is fully compatible with both conventional and enhanced CTCSS signalling operations and will implement the ‘All Call Code’ and ‘All Codes Monitor’ functions. Data for GPS The CMX882 facilitates Global Positioning by Satellite (GPS) by providing, in the Tx path, a 1200/2400 bps MSK data packet encoder (suitable for NMEA 0183 data transfer) incorporating interleaving, FEC, CRC and data scrambling. In the Rx path a 1200/2400 bps data packet decoder with automatic bit-rate recognition, 16-bit frame-sync detector, error correction, data de-scrambling and packet disassembly is available. With ultra low power requirements and graduated powersave, this product only requires a smaller, lower-power µC than existing FRS/PMR446 solutions, is available in compact SSOP and TSSOP packages.

Wireless Data Products CMX469A 1200/2400/4800 Baud FFSK Modem Selectable 1200, 2400 and 4800 Baud Data with Carrier Detect The CMX469A is a single-chip CMOS LSI circuit which operates as a full-duplex pinselectable 1200, 2400 or 4800 baud FFSK Modem.

Features  Selectable Data Rates: 1200/2400/4800 Baud  Full Duplex FFSK  Rx and Tx Bandpass Filters  Clock Recovery and Carrier Detect Facilities  Pin Selectable Xtal/Clock Inputs:  1.008MHz or 4.032MHz  Simple Control: No µP Required

The mark and space frequencies are 1200/1800, 1200/2400 and 2400/4800Hz respectively. Tone frequencies are phase continuous; transitions occur at the zero crossing point. Employing a common Xtal oscillator with a choice of two clock frequencies (1.008MHz or 4.032MHz) to provide baud-rate, transmit frequencies, and Rx and Tx synchronisation, the transmitter and receiver operate entirely independently including individual section powersave functions.

Supply Requirement Range: 2.7 to 5.5V

The CMX469A includes on-chip circuitry for Carrier Detect and Rx Clock recovery, both of which are made available as output pins. Rx, Tx and Carrier Detect paths each contain a bandpass filter to ensure the provision of optimum signal conditions both in the modem and for the Tx modulation circuitry.

Applications  Data-Over-Radio  PMR and Cellular Radio Signalling  Automatic Vehicle Location (Differential GPS) Links  Portable Data Terminals  Personal/Cordless Telephone

The CMX469A demonstrates a high sensitivity and good bit-error-rate under adverse signal conditions; the carrier detect time constant is set by an external capacitor, whose value should be arranged as required to further enhance this product’s performance in high noise environments. This low-power device requires few external components and is available in small outline plastic SOIC and TSSOP packages.

The CMX589A is a single-chip full-duplex synchronous data pump/modem designed for Wireless Data Applications. Employing Gaussian filtering for Minimum Shift Keying (GMSK) baseband modulation applications, the CMX589A features a wide range of available data rates from 4000 to 200000 (200k) b/s. Data Rates and the choice of BT (0.3 or 0.5) are pin programmable to provide for different system requirements. The Tx and Rx digital data interfaces are bit serial, synchronized to generated Tx and Rx data clocks. Separate Tx and Rx Powersave inputs allow full or half-duplex operation. Rx input levels can be set by suitable AC and DC level adjusting circuitry built with external components around an on-chip Rx Input Amplifier. Acquisition, Lock, and Hold of Rx data signals are made easier and faster by the use of Rx Control Inputs to clamp, detect, and/or hold input data levels and can be set by the µProcessor as required. The Rx S/N output provides an indication of the quality of the received signal.

The CMX7143 is a unique, highly-flexible single IC product offering wide-ranging wireless data operations in one hardware package. This unique way of operating means that you can produce an individual end-product platform operable to (currently) three different schemes. A saving in time, cost and materials. Built on CML’s proprietary FirmASIC technology, this IC can be configured by a Function Image (FI) file to one of three individual functions:

  

Operation, in the host equipment, to alternative data schemes is achieved literally at the ‘press of a button’. FirmASIC IC function and configuration is achieved by the loading of a compact Function Image file at start-up or when a change of data scheme is required. Function Image files, which are downloadable from the CML website, can be easily 'swopped' in the field by the host µC to allow the system to operate to an entirely different (data) scheme. This device utilises CML’s proprietary FirmASIC component technology.

Supply Requirement Range: 3.0 to 3.6 V

On-chip sub-systems are configured by a Function Image: this is a data file that is uploaded during device initialisation and defines the device's function and feature set.

The CMX7163 QAM Modem is a low power half-duplex device supporting multiple channel spacings under host microcontroller (µC) control. Its Function Image (FI) is loaded to initialise the device and determine modulation types. The 7163FI-4.x supports 4/16/32/64-QAM modulations up to 96kbps in a 25kHz channel, with channel estimation and equalization to provide robust performance under realistic channel conditions. Flexible bit rates support a wide range of applications requiring a selectable bit rate and robustness. Forward error correction and raw modes are available and support user-defined packet structures to support a range of applications. For greater flexibility, different rate FEC modes are provided. Receive signal quality measurement is supported, making a useful assessment of link conditions. High performance digital IF filters may be reconfigured to support multiple channel spacings via host command. This feature may eliminate the need to switch between multiple discrete IF filters. An integrated analogue interface supports 'direct connection' to zero IF I/Q radio transceivers with few external components; no external codecs are required. Intelligent auxiliary ADC, DAC and GPIO subsystems perform valuable functions and minimise host interaction and host I/O resources. Two synthesised system clock generators develop clock signals for off-chip use. A C-BUS/SPI master interface expands host C-BUS/SPI ports to control external devices. The device utilises CML's proprietary FirmASIC component technology. On-chip sub-systems are configured by a Function Image data file that is uploaded during device initialisation and defines the device's function and feature set. The Function Image can be loaded automatically from a host µC over the C-BUS serial interface or from an external memory device. The device's functions and features can be enhanced by subsequent Function Image releases, facilitating in-the-field upgrades. Adaptive Coded Modulation (ACM) features allow modulation type and block format to be changed on the fly via over-air commands that control a receiving CMX7164. They enable a Tx host to select optimum modulation and coding per burst to suit application message size, link channel quality and can also relax required Rx host message parsing speed.

 Licence-Free Radio Data  ISM-Band Radio Schemes

The CMX909B is a half-duplex Gaussian Minimum Shift Keyed (GMSK) BT = 0.3 modem data pump with on-chip packet data handling. GMSK modulation optimises the data throughput for a given bandwidth RF channel and the on-chip packet data handling relieves the host µC of regular processing tasks, such as maintaining Bit and Frame Synchronisation, Block Formatting, CRC and FEC Error Processing, Data Interleaving and Scrambling. The demodulator uses decision feedback equalisation techniques to reduce the channel distortion effects and enhance the receiver performance without the computational overhead of maximum likelihood (Viterbi) estimation methods. The CMX909B is pin, function and software backwards compatible with the FX909A and MX909A modems and also uses the same external components. It offers improved performance, higher data rates and lower voltage operation, as well as handling the recent R14N extension to Mobitex for short block frames. The CMX909B also offers 2-strength Xtal driver circuitry – for wider choice of xtals, optional zero-error or one-error frame sync detection, multiple powersave options – for intelligent power management, and availability in 24-pin TSSOP, SSOP (low-height) and PDIP package options. The CMX909B is ideally suited to wireless data applications such as Mobitex terminals, wireless telemetry, licence-free radio data and ISM band radio schemes.

The RALCWI Vocoder comprises four independent functions which are selectable by the host: Voice Encoder, FEC Encoder, Voice Decoder and FEC Decoder. The CMX618 includes an integrated voice CODEC, offering a complete analogue voice to low bit rate vocoded data function, with integrated channel filters removing the need for external components, whereas the CMX608 requires an external voice CODEC.

Ancillary Audio Functions: •Voice Activity Detector •Comfort Noise Generator •DTMF and Single Tone Regeneration Voice Store and Retrieve, Encryption and Noise Gate. Fine Analogue Output Gain. Voice Activity Detector, DTMF/Tone generator, comfort noise generator, soft decision decoding Supply Requirement Range: 3.0 to 3.6 V

The devices all operate from a dual power supply (1.8V and 3.3V) and are available in both 48-pin LQFP (L4) and 48-pin VQFN (Q3) packages. In encode mode, the voice encoder uses a 20ms voice frame size with 2 programmable bit rates: 2400bps or 2750bps. The optional FEC encoder performs channel coding of the encoded voice (2400bps or 2750bps, depending on the selected mode) and forms an encoded, interleaved bit-stream of 3600bps (216 bits per 60ms packet or 288 bits per 80ms packet).

Applications  dPMR, PMR, LMR, DMR TDMA, FDMA

      

In decode mode, the optional FEC decoder performs de-interleaving and channel decoding of the coded bit-stream (216 bits per 60ms packet or 288 bits per 80ms packet) and forms an error-corrected bit-stream of encoded voice at 2400bps or 2750bps rate, depending on the selected mode.

Digital Trunking, Digital WLL Digital-voice Scrambling and Encryption Voice-storage and Playback Systems Messaging Systems

The FEC decoder can optionally use "soft decision" metrics to improve its decoding ability. The voice decoder then converts the error-corrected bit-stream back into a digitised voice signal. Soft Decision Decoding (SDD), Discontinuous Transmission detection (DTX), Voice Activity Detection (VAD) and Comfort Noise Generation (CNG) functions are also included, to further enhance the overall performance.

VoIP Systems Voice Pagers Regenerative Digital Voice Repeaters

Single (STD) and Dual (DTMF) Tones can be detected and sent separately in the coded bit-stream, then regenerated at the far end.

A significant feature of the CMX7011 is the programmable push-to-talk (PTT) buffer which offers instant voice capture in transmit mode. The PTT buffer temporarily stores the initial part of the speech and can eliminate voice clipping caused by the time required to decode sub audio signals like CTCSS in the receiver, as well as to compensate for system delays caused by repeaters. Within the CMX7011's header frame is a user-programmable 8-bit address field which allows up to 256 individual user addresses to be defined. The device also offers a number of additional advanced features including Voice Storage and Retrieval, Secure Packet Data capability and Late/Re-entry protocol providing high performance in fading conditions. The CMX7011 uses CML's proprietary FirmASIC component technology, providing maximum flexibility with upgrade capability and a roadmap of future function enhancements.
