MAXIM MAX1471 handbook

The MAX1471 is a low power, CMOS, superheterodyne, RF dual-channel receiver designed to receive both amplitude-shift-keyed (ASK) and frequency-shift-keyed (FSK) data without reconfiguring the device or introducing any time delay normally associated with changing modulation schemes. The MAX1471 requires few external components to realize a complete wireless RF digital data receiver for the 300MHz to 450MHz ISM bands. The MAX1471 includes all the active components required in a superheterodyne receiver including: a low-noise amplifier (LNA), an image-reject (IR) mixer, a fully integrated phase-locked loop (PLL), local oscillator (LO), 10.7MHz IF limiting amplifier with received-signal-strength indicator (RSSI), low-noise FM demodulator, and a 3V voltage regulator. Differential peak-detecting data demodulators are included for both the FSK and ASK analog baseband data recovery. The MAX1471 includes a discontinuous receive (DRX) mode for low-power operation, which is configured through a serial interface bus. The MAX1471 is available in a 32-pin thin QFN package and is specified over the automotive -40°C to +125°C temperature range.
