FX589 Overview
The FX589 is a single-chip modem employing Gaussian Minimum Shift Keying (GMSK) modulation. Data rates of 4kb/s to 64kb/s and the choice of BT to 0.3 or 0.5 are pin-programmable functions to suit radio data channel bandwidth requirements. The Rx and Tx digital data interfaces are bit-serial and synchronised to Rx and Tx data clocks generated by the modem.
