sl6609a Zarlink Semiconductor, sl6609a Datasheet - Page 2

• Manufacturer Part Number: sl6609a
• Description: Direct Conversion Fsk Data Receiver
• Manufacturer: Zarlink Semiconductor

operation up to 470MHz. The design is based on the SL6609
receiver and is a pin for pin product upgrade. The device
integrates all functions to translate a binary FSK modulated
RF signal into a demodulated data stream. Adjacent channel
rejection is provided using tuneable gyrator filters. To assist
operation in the presence of large interfering signals both RF
and audio AGC functions are provided.
sourcing up to 5mA, a battery flag and the facility of incorporating
a more complex post detection filter off-chip. Both battery flag
and data outputs have open collector outputs to ease their
interface with other devices.
