Low-voltage digital IF receiver  
SA637  
DESCRIPTION  
FEATURES  
PIN CONFIGURATION  
The SA637 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 SA637 is available in SSOP  
(shrink small outline package).  
V = 2.7 to 5.5V

The SA637 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.
