topGeneral description
The SA636 is a low-voltage high performance monolithic FM IF system with high-speed RSSI
incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector,
logarithmic received signal strength indicator (RSSI), voltage regulator, wideband data output and fast RSSI
op amps. The SA636 is available in 20-lead SSOP (shrink small outline package).
The SA636 was designed for high bandwidth portable communication applications and will function down
to 2.7V. The RF section is similar to the famous SA605. The data output has a minimum bandwidth of
600kHz. This is designed to demodulate wideband data. The RSSI output is amplified. The RSSI output has
access to the feedback pin. This enables the designer to adjust the level of the outputs or add filtering.
SA636 incorporates a power down mode which powers down the device when Pin 8 is low. Power down
logic levels are CMOS and TTL compatible with high input impedance.
