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.
