2 / 20 page ADVANCE INFORMATION DS4015 - 2.5 JULY 1995 This device is an advanced direct conversion receiver for 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. The device also includes a 1 volt regulator capable of 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. FEATURES s Very low power operation - typ 3.0mW s Single cell operation for most of the device.
