SL6679

Direct Conversion FSK Data Receiver

Preliminary Information

The SL6679 is an advanced Direct Conversion FSK Data

Receiver for operation up to 450 MHz. The device integrates all

functions to convert a binary FSK modulated RF signal into a

demodulated data stream.

Adjacent channel rejection is provided using tuneable gyrator

filters. RF and audio AGC functions assist operation when large

interfering signals are present and an automatic frequency control

(AFC) function is provided to extend centre frequency acceptance.

Supersedes September 1996 version, DS4410 - 1.5
