308MHz/315MHz/418MHz/433.92MHz

Low-Power, FSK Superheterodyne Receiver

MAX7042

General Description

Features

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.

o +2.4V to +3.6V or +4.5V to +5.5V Single-Supply

Operation

o Four User-Selectable Carrier Frequencies

308, 315, 418, and 433.92MHz

o -110dBm RF Input Sensitivity at 315MHz

o -109dBm RF Input Sensitivity at 433.92MHz

o Fast Startup (< 250µs)

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.

o Small 32-Pin TQFN Package

o Low Operating Supply Current

6.2mA Continuous

20nA Power-Down

o Integrated PLL, VCO, and Loop Filter

o 45dB Integrated Image Rejection

o Selectable IF BW with External Filter

o Positive and Negative Peak Detectors

o RSSI Output

The MAX7042 is available in a 32-pin TQFN and is

specified over the automotive -40°C to +125°C tem-

perature range.
