Description
The SA58641 is a 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.
Features
- Wideband data output (600 kHz minimum).
- Fast RSSI rise and fall times.
- Low power consumption: 7.5 mA typical at 5 V.
- Mixer input to >500 MHz.
- Mixer noise figure of 12 dB at 240 MHz.
- Crystal 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 RSSI with a dynamic range in excess of 90 dB.
- RSSI output inter.
