U2762B

900-MHz ISM Band Receiver

Description

The receiver IC U2762B-B is specifically designed for

cordless telephone applications in the 900-MHz ISM

band. It is manufactured using TEMIC’s advanced UHF

process. The IC consists of a 900-MHz RF amplifier and

mixer, 10.7-MHz IF amplifier, limiter, RSSI, quadrature

demodulator and comparator for the bit-slicer function.

The device features 2.9-V operation. In conjunction with

TEMIC’s transmitter IC U2763B-B and the PLL

U2781B, a complete ISM RF IC kit is available which fits

perfectly with AMD’s PhoX controllers AM79C432A

and AM79C433.

Electrostatic sensitive device.

Observe precautions for handling.

Features

Single-conversion receiver with 10.7-MHz IF

Comparator for bit slicer integrated

Temperature-compensated RSSI with 65 dB

dynamic range

Supply-voltage range 2.7 V to 3.3 V

Only 17 mA typical current consumption

Few external components

SSO28 package

Benefits

Low filter costs due to 10.7-MHz single conversion

Very low count of external components saves PCB

space and costs

Low current consumption results in very long

stand-by time of approximately 7 days
