19-3704; Rev 0; 5/05  
308MHz/315MHz/418MHz/433.92MHz  
Low-Power, FSK Superheterodyne Receiver  
General Description  
Features  
♦ +2.4V to +3.6V or +4.5V to +5.5V Single-Supply  
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.  
Operation  
♦ Four User-Selectable Carrier Frequencies  
308, 315, 418, and 433.92MHz  
♦ -110dBm RF Input Sensitivity at 315MHz  
♦ -109dBm RF Input Sensitivity at 433.92MHz  
♦ 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.  
♦ Small 32-Pin Thin QFN Package  
♦ Low Operating Supply Current  
6.2mA Continuous  
20nA Power-Down  
♦ Integrated PLL, VCO, and Loop Filter  
♦ 45dB Integrated Image Rejection  
♦ Selectable IF BW with External Filter  
♦ Positive and Negative Peak Detectors  
♦ RSSI Output  
The MAX7042 is available in a 32-pin thin QFN and  
is specified over the automotive -40°C to +125°C  
temperature range.
