SL6619
Direct Conversion FSK Data Receiver
Data Sheet
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
• Very Low Power Operation from Single Cell
• Superior Sensitivity
• Operation at 512, 1200 and 2400 Baud
• On Chip 1 Volt Regulator
• 1mm Height Miniature Package
• Automatic Frequency Control Function
• Programmable Post Detection Filter
• AGC Detection Circuitry
• Power Down Function
• Battery Strength Indicator
Applications
• Pagers, including Credit Card, PCMCIA and
Watch Pagers
• Low Data Rate Receivers, e.g. Security Systems
