MAX7042ATJ+

MAX7042ATJ+ is a fully integrated, low-power, CMOS superheterodyne RF receiver in a 32-pin TQFN-EP package. It is designed to receive frequency-shift-keyed (FSK) data at rates up to 66kbps nonreturn-to-zero (NRZ) (33kbps Manchester). The MAX7042 requires only a few external components to realize a complete wireless RF receiver at 308, 315, 418, and 433.92MHz. The MAX7042 includes all the active components required in a superheterodyne receiver including a low noise amplifier (LNA), an image-rejection (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 regulator. Differential peak-detecting data demodulators are included for baseband data recovery. Typical applications include remote keyless entry, tire-pressure monitoring, home and office lighting control, remote sensing, smoke alarms, home automation, local telemetry systems and security systems.
