308MHz/315MHz/418MHz/433.92MHz
Low-Power, FSK Superheterodyne Receiver
General Description
The MAX7042 fully integrated, low-power, CMOS
superheterodyne RF receiver 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.
The MAX7042 is available in a 32-pin TQFN and is
specified over the automotive -40°C to +125°C tem-
perature range.
