Brief Description

The FX579 is a single chip, low cost, low current integrated circuit that performs the baseband

functions of a half duplex GMSK modem and is intended for use in FM radio data links. This general

purpose modem is suitable for data rates in the region of 4 to 40 kbits/sec, at a BT of 0.3 or 0.5.

The Tx and Rx data lines share a common pin and data is synchronised to a Tx/Rx data clock

generated by the modem. A single ACQUIRE line is provided to assist with acquisition of Rx data

signals.
