TEF6701HL - Car radio tuner front-end

Description

The TEF6701HL is a single chip car radio tuner for AM, FM standard, FM In-Band On-Channel Digital Audio Broadcast (IBOC DAB) and weather band providing gain controlled output of FM IF and AM IF2 for a car IF DSP IC (e.g.

AM double conversion tu

Features

  • s FM mixer for conversion of FM RF (64 MHz to 108 MHz and US weather band) to an IF of 10.7 MHz; the mixer provides inherent image rejection and can be switched from low injection to high injection Local Oscillator (LO) via the I2C-bus; two different mixer conversion gains can be selected via the I2C-bus s AGC PIN diode drive circuit for FM RF AGC; AGC detection at FM mixer input; the AGC PIN diode drive can be activated via the I2C-bus as a local function for search tuning; AGC threshold is a p.
