Introduction
Welcome 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.

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.

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.

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.

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.

FRS Text Messaging
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.

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.

Digital Software Defined Radio (SDR)
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.

 Mobile Data Systems
 Wireless Telemetry
 DataTAC Terminals
The CMX969 is a CMOS integrated circuit that contains all of the baseband signal processing and
Medium Access Control (MAC) protocol functions required for a high performance DataTAC dual
mode RD-LAP 19200bps and MDC 4800bps FSK Wireless Packet Data Modem suitable for use
with the Motient/ARDIS network. It interfaces with the modem host processor and the radio
modulation/demodulation circuits to deliver reliable two-way transfer of the application data over
the wireless link.
The CMX969 assembles application data received from the host processor, adds forward error
correction (FEC) and error detection (CRC) information and interleaves the result for burst-error
protection. After adding symbol and frame synchronisation codewords and channel status
symbols, it converts the packet into a filtered analogue baseband signal for modulating the radio
transmitter.
In receive mode, the CMX969 performs the reverse function using the analogue baseband
signals from the receiver frequency discriminator. After error correction and removal of the packet
overhead, the recovered application data is supplied to the host processor. Any residual
uncorrected errors in the data will be flagged. A readout of the received signal quality is also
provided.
An optional Autonomous Frame Sync Detection function is provided for use in Motient/ARDIS
systems employing Single Frequency Re-use operation. The CMX969 uses signal filtering, data
block formats and FEC/CRC algorithms compatible with the MDC and RD-LAP over-air standards.
The device is programmable to operate from a wide choice of Xtal frequencies and is available in
24 pin PDIP, SSOP and TSSOP packages.

 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.

Real-time Digital Voice Encryption
The CMX7011 is a flexible, half-duplex, digital voice encryption processor that provides the
digital advantage to conventional analogue two-way radios. Digital voice scrambling is a key
feature of the device, transmitting and receiving secure encrypted voice via an embedded
robust data modem.
Voice Store/Retrieve, Packet data
Air Interface Protocol
Instant Voice Capture
The device allows simple implementation and configuration within existing designs and is
intended to be added to a radio via an accessory module or "feature socket". The device is
simple to control via a small, low-power microcontroller.
Flexible 256 User Addressing
Embedded RALCWI Vocoder
Licence Included (Royalty Free)
The CMX7011 offers good quality speech which is better than that of traditional analogue
radios at the fringes of reception and, using the internal digital encryption algorithm,
significantly higher levels of security are achieved.
Embedded Audio-band Modem
Supply Requirement Range: 3.0 to 3.6 V
Applications
 Digital Voice Encryption on Analogue
Radio
 Wireless Door Entry/Gate Access
 Analogue Radio Add-on
 Digital Advantage for Analogue Radio
Embedded within the CMX7011 is CML's proven and reliable RALCWI (Robust Advanced
Low Complexity Waveform Interpolation) vocoder providing near toll quality speech at a low
bit rate.
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.
The CMX188 is a 'plug and play' (no Function Image upload required) version of the
CMX7011. The CMX188 is pin and function compatible with the CMX7011 and is available
for high quantity applications. Please contact CML for further details
