DESCRIPTION
The SA676 is a low-voltage monolithic FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, logarithmic received signal strength indicator (RSSI), voltage regulator and audio and RSSI op amps. The SA676 is available in a 20-pin SSOP (shrink small outline package).

FEATURES
• Low power consumption: 3.5mA typical at 3V
• Mixer input to >100MHz
• Mixer conversion power gain of 17dB at 45MHz
• XTAL oscillator effective to 100MHz (L.C. oscillator or external oscillator can be used at higher frequencies)
• 102dB of IF Amp/Limiter gain
• 2MHz IF amp/limiter small signal bandwidth
• Temperature compensated logarithmic Received Signal Strength Indicator (RSSI) with a 70dB dynamic range
• Low external component count; suitable for crystal/ceramic/LC filters
• Audio output internal op amp
• RSSI output internal op amp
• Internal op amps with rail-to-rail outputs
• ESD protection: Human Body Model 2kV Robot Model 200V

APPLICATION
• Cordless phones
