315MHz/434MHz ASK Superheterodyne

Receiver

MAX7034

General Description

Features

♦ Optimized for 315MHz or 433.92MHz Band

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 frequencies). The receiver has an RF sensi-

tivity of -114dBm. With few external components and a

low-current power-down mode, it is ideal for cost-sensi-

tive and power-sensitive applications typical in the

automotive and consumer markets. The MAX7034 con-

sists 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.

♦ Operates from Single +5.0V Supply

♦ Selectable Image-Rejection Center Frequency

♦ Selectable x64 or x32 f_LO/f_XTALRatio

♦ 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

The MAX7034 is available in a 28-pin TSSOP package

and is specified over the automotive (-40°C to +125°C)

temperature range.
