Brief Description

The FX529 is a single-chip CMOS 1200 baud FFSK

Modem, designed primarily for use in trunked radio

systems but may also be employed in other general

purpose radio or line data communication applications.

This device conforms to both the PAA 1382 French

trunked radio, and the proposed ETSI

(“1011010000110011”) or SYNT

(“0100101111001100”) word detected in the receive

mode.

An on-chip Xtal/clock generator requiring an

external 4.032MHz Xtal or clock input provides all

microcircuit filter sampling clocks and modem timings

whilst also supplying a “Clock “ 4” output (1.008MHz).

Pin and function compatible with the FX429, the

FX429 data sheet should be consulted when using this

device

The FX529, which has a powersaving facility,

requires a single 5-volt power supply and is available

in both cerdip DIL and plastic SMD packages.

I-ETS 300 230 “Binary Interchange of Information and

Signalling” specifications.

The FX529 is full duplex at 1200 baud and includes

an 8-bit parallel microprocessor interface and a

programmable timer which may be set for interrupt

periods of between 8 and 120 bits.

Preamble data and an error-check word are

automatically generated in the transmit mode.

Error checking is performed and the 16-bit SYNC

CML Product Data

In the process of creating a more global image, the three standard product semiconductor

companies of CML Microsystems Plc (Consumer Microcircuits Limited (UK), MX-COM, Inc

(USA) and CML Microcircuits (Singapore) Pte Ltd) have undergone name changes and, whilst

maintaining their separate new names (CML Microcircuits (UK) Ltd, CML Microcircuits (USA)

Inc and CML Microcircuits (Singapore) Pte Ltd), now operate under the single title CML Micro-

circuits.

These companies are all 100% owned operating companies of the CML Microsystems Plc

Group and these changes are purely changes of name and do not change any underlying legal

entities and hence will have no effect on any agreements or contacts currently in force.

CML Microcircuits Product Prefix Codes

Until the latter part of 1996, the differentiator between products manufactured and sold from

MXCOM, Inc. and Consumer Microcircuits Limited were denoted by the prefixes MX and FX

respectively. These products use the same silicon etc. and today still carry the same prefixes.

In the latter part of 1996, both companies adopted the common prefix: CMX.
