SL6619
Direct Conversion FSK Data Receiver
August 2005
The SL6619 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.
Features
