General 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.

Features
I
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 I
2
C-bus; two different mixer
conversion gains can be selected via the I
2
C-bus
I
AGC PIN diode drive circuit for FM RFAGC; AGC detection at FM mixer input; the
AGC PIN diode drive can be activated via the I
2
C-bus as a local function for search
tuning; AGC threshold is a programmable and keyed function switchable via the
I
2
C-bus
I
Digital alignment circuit for bus controlled matching of oscillator tuning voltage to FM
antenna tank circuit tuning voltage
I
Buffer output for weather band flag
I
FM IF linear amplifier with high dynamic input range; amplifier gain can be switched to
two different positions via the I
2
C-bus
I
FM IFAGC with multiplexed inputs for FM and In-Band On-Channel Digital Audio
Broadcast (IBOC DAB)
I
Buffer amplifier for FM IBOC DAB IF bypassing second IF filter can be activated via
I
2
C-bus
I
AM mixer 1 for conversion of AM RF to AM IF1 10.7 MHz
I
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 I
2
C-bus
I
AM noise blanker with blanking at AM IF2; AM noise blanker can be deactivated via
the I
2
C-bus
I
AM mixer 2 for conversion of AM IF1 to AM IF2 450 kHz
