19-3272; Rev 4; 9/11  
315MHz/434MHz Low-Power, 3V/5V  
ASK/FSK Superheterodyne Receiver  
MAX471  
General Description  
Features  
The MAX1471 low-power, CMOS, superheterodyne, RF  
dual-channel receiver is designed to receive both ampli-  
tude-shift-keyed (ASK) and frequency-shift-keyed (FSK)  
data without reconfiguring the device or introducing any  
time delay normally associated with changing modula-  
tion schemes. The MAX1471 requires few external com-  
ponents to realize a complete wireless RF digital data  
receiver for the 300MHz to 450MHz ISM bands.  
o ASK and FSK Demodulated Data on Separate  
Outputs  
o Specified over Automotive -40°C to +125°C  
Temperature Range  
o Low Operating Supply Voltage Down to 2.4V  
o On-Chip 3V Regulator for 5V Operation  
o Low Operating Supply Current  
7mA Continuous Receive Mode  
1.1µA Deep-Sleep Mode  
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.  
o Discontinuous Receive (DRX) Low-Power  
Management  
o Fast-On Startup Feature < 250µs  
o Integrated PLL, VCO, and Loop Filter  
o 45dB Integrated Image Rejection  
o RF Input Sensitivity*  
ASK: -114dBm  
FSK: -108dBm  
o Selectable IF BW with External Filter  
The MAX1471 is available in a 32-pin thin QFN package  
and is specified over the automotive -40°C to +125°C  
temperature range.  
o Programmable Through Serial User Interface  
o RSSI Output and High Dynamic Range with AGC  
*0.2% BER, 4kbps, Manchester-encoded data, 280kHz IF BW
