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..
Features
- 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/limiter small signal bandwidth.
- Temperature compensated logarithmic RSSI with a 70 dB dynamic range.
- Low external component count; suitabl.
