SA636  
Low voltage high performance mixer FM IF system  
with high-speed RSSI  
Rev. 7 — 16 June 2016  
Product data sheet  
1. General 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) and HVQFN20 (quad flat package).  
The SA636 was designed for high bandwidth portable communication applications and  
will function down to 2.7 V. The RF section is similar to the famous SA605. The data  
output has a minimum bandwidth of 600 kHz. 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  
POWER_DOWN_CTRL pin is LOW. Power-down logic levels are CMOS and TTL  
compatible with high input impedance.  
2. Features and benefits  
Wideband data output (600 kHz minimum)  
Fast RSSI rise and fall times  
Low power consumption: 6.5 mA typical at 3 V  
Mixer input to >500 MHz  
Mixer conversion power gain of 11 dB at 240 MHz  
Mixer noise figure of 12 dB at 240 MHz  
XTAL oscillator effective to 150 MHz (LC oscillator to 1 GHz local oscillator can be  
injected)  
92 dB of IF amp/limiter gain  
25 MHz limiter small signal bandwidth  
Temperature compensated logarithmic Received Signal Strength Indicator (RSSI) with  
a dynamic range in excess of 90 dB  
RSSI output internal op amp  
Internal op amps with rail-to-rail outputs  
Low external component count; suitable for crystal/ceramic/LC filters  
Excellent sensitivity: 0.54 V into 50 matching network for 12 dB SINAD  
(Signal-to-Noise And Distortion ratio) for 1 kHz tone with RF at 240 MHz and IF at  
10.7 MHz  
10.7 MHz filter matching (330 )  
Power-down mode (ICC = 200 A)
