TEF6700HL

Car radio tuner front-end for digital IF


The TEF6700HL is a single chip car radio tuner for AM, FM standard, FM IBOC DAB and weather band providing gain controlled output of FM IF and AM IF2 for a car IF DSP IC (e.g. SAA7724H) including the following functions:

  • AM double conversion tuner for LW/MW/SW (31 m, 41 m and 49 m bands) with IF1 = 10.7 MHz and IF2 = 450 kHz
  • FM single conversion tuner to an IF frequency of 10.7 MHz with integrated image rejection for US FM, Europe FM, Japan FM, East Europe FM and weather band reception; all bands can be selected using high side or low side Local Oscillator (LO) injection
  • Tuning system includes VCO, crystal oscillator and PLL synthesizer on one chip.

Features and benefits

  • FM mixer for conversion of FM RF (64 to 108 MHz and US weather band) to 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
  • 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 programmable and keyed function switchable via the I²C-bus
  • Digital alignment circuit for bus controlled matching of oscillator tuning voltage to FM antenna tank circuit tuning voltage
  • Buffer output for weather band flag
  • FM IF linear amplifier with high dynamic input range; amplifier gain can be switched to two different positions via the I²C-bus
  • FM IF AGC with multiplexed inputs for FM and In-Band On-Channel Digital Audio Broadcast (IBOC DAB)
  • Buffer amplifier for FM IBOC DAB IF bypassing second IF filter can be activated via I²C-bus
  • AM mixer 1 for conversion of AM RF to AM IF1 10.7 MHz
  • AM RF PIN diode drive circuit and RF JFET conductance control by AGC cascode drive circuit; AGC threshold detection at AM mixer 1 and IF2 AGC input; threshold is programmable via the I²C-bus
  • AM noise blanker with blanking at AM IF2; AM noise blanker can be deactivated via the I²C-bus
  • AM mixer 2 for conversion of AM IF1 to AM IF2 450 kHz
  • AM IF2 AGC
  • Multiplexer to output AM IF2 AGC and FM IF AGC to a car IF DSP IC (e.g. SAA7724H)
  • AM/FM RF AGC monitor output
  • Level detector for AM and FM with temperature compensated output voltage; starting point and slope of level output is programmable via the I²C-bus
  • IF counter for AM IF2 and FM IF
  • LC tuner oscillator providing mixer frequencies for FM mixer and AM mixer 1
  • Crystal oscillator providing mixer frequencies for AM mixer 2 and reference for synthesizer PLL, IF count and timing for Radio Data System (RDS) update
  • Fast synthesizer PLL tuning system with local control for inaudible RDS updating
  • Timing function for RDS update algorithm and control signal output for a car IF DSP IC (e.g. SAA7724H)
  • Three hardware programmable I²C-bus addresses; pin BUSENABLE; two software controlled flag outputs
  • Several test modes for fast IC and system tests.
