MAX7042ATJ-T 数据手册

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.
