MAX7034

315MHz/434MHz ASK Superheterodyne

Receiver

General Description

Features

The MAX7034 fully integrated low-power CMOS super-

heterodyne receiver is ideal for receiving amplitude-shift-

keyed (ASK) data in the 300MHz to 450MHz frequency

range (including the popular 315MHz and 433.92MHz fre-

quencies). The receiver has an RF sensitivity of -114dBm.

With few external components and a low-current power-

down mode, it is ideal for cost-sensitive and power-sensi-

tive applications typical in the automotive and consumer

markets. The MAX7034 consists of a low-noise amplifier

(LNA), a fully differential image-rejection mixer, an on-

chip phase-locked loop (PLL) with integrated voltage-

controlled oscillator (VCO), a 10.7MHz IF limiting amplifier

stage with received-signal-strength indicator (RSSI), and

analog baseband data-recovery circuitry.

● Optimized for 315MHz or 433.92MHz Band

● Operates from Single +3.3V/+5.0V Supply

● Selectable Image-Rejection Center Frequency

● Selectable x64 or x32 f /f

Ratio

LO XTAL

● Low (< 6.7mA) Operating Supply Current

● < 3.0μA Low-Current Power-Down Mode for Efficient

Power Cycling

● 250μs Startup Time

● Built-In 44dB RF Image Rejection

● Excellent Receive Sensitivity Over Temperature

● -40°C to +125°C Operation

● -40°C to +105°C Operation (3.0V to 3.6V Supply)

The MAX7034 is available in a 28-pin (9.7mm x 4.4mm)

TSSOP package and is specified over the automotive

(-40°C to +125°C) temperature range.
