DESCRIPTION
The SA647 is a low-voltage high performance monolithic digital
system with high-speed RSSI incorporating a mixer, oscillator with
buffered output, two limiting intermediate frequency amplifiers, fast
logarithmic received signal strength indicator (RSSI), voltage
regulator, RSSI op amp and power down pin. The SA647 is
available in TSSOP (thin shrink small outline package).
The SA647 was designed for portable digital communication
applications and will function down to 2.7V. The limiter amplifier has
differential outputs with 2MHz small signal bandwidth. The RSSI
output has access to the feedback pin. This enables the designer to
level adjust the outputs or add filtering.
