General Description
SA626 General Description
The SA626 is a low-voltage high performance monolithic FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, high speed logarithmic received signal strength indicator (RSSI), voltage regulator and audio and fast RSSI op amps. The SA626 is available in 20-lead SOL (surface-mounted small outline large package) and 20-lead SSOP (shrink small outline package).
The SA626 was designed for high bandwidth portable communication applications and will function down to 2.7V. The RF section is similar to the famous NE605. The audio and RSSI outputs have amplifiers. The RSSI output has access to the feedback pin. This enables the designer to level adjust the outputs or add filtering.
SA626 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.
