High performance low power mixer FM IF system with high-speed RSSI
SA625
DESCRIPTION
The SA625 is pin-to-pin compatible with the SA605, but has faster RSSI rise and fall times. The SA625 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, and voltage regulator. The SA625 combines the functions of Signetics’ SA602A and SA624.
