SA624 - High performance low power FM IF system with high-speed RSSI
The SA624 is pin-to-pin compatible with the SA604A, but has faster RSSI rise and fall time.
The SA624 is an improved monolithic low-power FM IF system incorporating two limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic received signal strength indicator, and voltag
