SA58640 datasheet

Description :

The SA58640 is a low-voltage monolithic FM IF system incorporating a mixer/oscillator,
two limiting intermediate frequency amplifiers, quadrature detector, logarithmic RSSI,
voltage regulator and audio and RSSI operational amplifiers. The SA58640 is available in
a 20-pin SSOP package.

„ Low power consumption: 5.0 mA typical at 5 V
„ Mixer input to >100 MHz
„ Mixer conversion power gain of 17 dB at 45 MHz
„ Crystal oscillator effective to 100 MHz (LC oscillator or external oscillator can be used
at higher frequencies)
„ 102 dB of IF amplifier/limiter gain
„ 2 MHz IF amplifier/limitersmall signal bandwidth
„ Temperature compensated logarithmic RSSI with a 70 dB 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 2 kV; robot model 200 V
