Product specification

High performance low power mixer FM IF system

with high-speed RSSI

SA627

DESCRIPTION

PIN CONFIGURATION

The SA627 has faster RSSI rise and fall times. The SA627 is a high

performance monolithic low-power FM IF system incorporating a

mixer/oscillator, two limiting intermediate frequency amplifiers,

quadrature detector, muting, logarithmic received signal strength

indicator (RSSI) with fast rise and fall time, voltage regulator and

frequency check/limiter out (–). The SA627 also has an extra limiter

output. This signal is buffered from the output of the limiter and

provides a negative (–) limiter output. This can be used to provide a

frequency check function. The SA627 is available in 20-lead SOL

(surface-mounted miniature package) and 20-lead SSOP (shrink

small outline package).
