TEF6862 Datasheet Car Radio Enhanced Selectivity Tuner

Manufacturer: NXP Semiconductors

Overview: .. TEF6862 Car Radio Enhanced Selectivity Tuner (CREST) Rev. 01 — 14 September 2006 Product data sheet 1.

General Description

The TEF6862 is a single-chip car radio tuner for AM, FM and weather band reception providing AM double conversion for LW, MW and full range SW (11 m to 120 m bands) with IF1 = 10.7 MHz and IF2 = 450 kHz.

FM double conversion to IF1 = 10.7 MHz and IF2 = 450 kHz with integrated image rejection for both IF1 and IF2;

integrated IF filter with variable bandwidth and automatic bandwidth control algorithm with flexibility via the I2C-bus;

Key Features

  • I High dynamic range FM front-end mixer for conversion of FM RF (65 MHz to 108 MHz and USA weather band) to an IF frequency of 10.7 MHz; mixer provides inherent image rejection which can be switched from low injection LO to high injection LO via the I2C-bus I FM front-end AGC PIN diode drive circuit; AGC detection at the FM font-end mixer input and the IF filter input; AGC threshold for detection at the mixer input is programmable and keyed AGC function can be selected via the I2C-bus; the AGC PI.
