Description

The FX829 is a low voltage CMOS integrated circuit, designed to provide the baseband audio and system signal-processing functions required for PAMR or PMR trunked radio applications. It operates in half-duplex mode under serial-bus control of the host µC.

The FX829 incorporates a dual-rate 1200/2400bps FFSK modem, with a software-flexible choice of synchronisation codewords, data run-length and CRC checking to suit a wide range of applications.These features allow very flexible handling of non-prescribed data on traffic channels in addition to the network signalling sent on control channels. A 16 character DTMF encoder is available in the transmit mode. The two-point modulation output has software programmable level-adjustment.

The audio processing stages of FX829 include transmit and receive filtering, to the standards specified for 12.5kHz and 25kHz PAMR/PMR channel operation, plus transmit deviation limiting and a programmable Rx volume control. Power saving is automatic when audio functions are deselected.

The FX829 is designed for use in radios compatible with MPT1327, PAA1382 and ETS 300 086 trunking standards. Its features and flexibility ensure that it is equally suitable for use with modified or proprietary standards.
