This device conforms to both the PAA 1382 French trunked radio, and the proposed ETSI 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 ("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. 1 FX529 - Brief Specification Function Supply Voltage Range Supply Current Control Duplex Data Rate Xtal/Clock Frequency Package Styles FFSK Modem for trunked radio systems 4.5 to 5.5 volts (5.0V) 7.0 mA maximum 8-bit parallel Full 1200 baud 4.032 MHz 24-pin cerdip DIL (FX529J) 24-pin PLCC (FX529LG) 24-pin PLCC (FX529LS) VDD VBIAS TRANSMIT OUTPUT RECEIVE INPUT 1 2 3 4 24 23 22 21 20 19 18 17 16 15 14 13 CLOCK 4 VSS IRQ A2 STROBE A1 A0 D7 D6 D5 D4 VSS VDD 'CD' TIME CONSTANT XTAL/CLOCK XTAL D0 D1 D2 D3 5 6 7 8 9 10 11 12 FX529J VSS D0 D1 D2 D3 D4 D5 D6 D7 MICROPROCESSOR DATA INTERFACE Package Styles Available FX529J 24-pin cerdip DIL (J4) FX529LG 24-pin quad plastic encapsulated bent and cropped (L1) FX529LS 24-lead plastic leaded chip carrier (L2) Full details of this product are available from CML or its distributors CML does not assume any responsibility for the use of any circuitry described.

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.
