The design is based on the SL6609A but is specifically designed for use in very small pagers i.e. credit card sized, where local oscillator re-radiation is a problem. This design has overe this difficulty. The device also includes a 1 volt regulator capable of sourcing up to 5m A, a battery flag and the facility of incorporating a more plex post detection filter off-chip. Both battery flag and data outputs have open collector outputs to ease their interface with other devices. 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.
