Brief Description

The FX589 is a single-chip modem employing

Acquisition, lock and hold of Rx data signals is made

easier and faster by the use of Rx Control Inputs to clamp,

detect and/or hold input data levels and can be set by the

system µProcessor as required.

Indication is available, from the Rx S/N output, as to the

quality of the received signal.

The FX589 design features a low-current analogue/digital

ASIC process offering significantly lower current

consumption than DSP technology. For data rates up to

32kb/s the FX589 draws typically 1.5mA at 3.0 volts V_DDand

for data rates up to 64kb/s at 5.0 volts, typically 4.0mA.

This low-power CMOS microcircuit is available in both

24-pin plastic DIL and Small Outline (SOIC and SSOP)

packages.

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. Separate Rx and Tx Powersave/Enable

inputs allow for full- or half-duplex operation.

Rx input levels can be set by a suitable ac and dc

level adjusting circuit built, with external components,

around an on-chip Rx input amplifier.
