Description

Features:

·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
·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

[1] To avoid damages and wrong operation it is necessary to keep all 8.5 V supply voltages at a higher level than any 5 V supply voltage.
This is also necessary during power-on and power-down sequences. Precautions have to be provided in such a way that interferences
can not pull down the 8.5 V supply below the 5 V supply.

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. 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.
