1. General description
2. Features
The TEF6721HL 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 combined
AM and FM gain controlled differential Intermediate Frequency (IF) output for the
SAF7730H including the following functions:
TEF6721HL
Car radio tuner front-end for digital IF
Rev. 04 — 20 December 2005
FM mixer for conversion of FM Radio Frequency (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
Automatic Gain Control (AGC) PIN diode drive circuit for FM RF AGC; AGC detection
at FM mixer input and IF AGC amplifier input; AGC threshold for detection at FM mixer
input is a programmable and keyed function switchable via the I
diode drive can be activated via the I
AM mode the AGC PIN diode drive can be activated via the I
Digital alignment circuit for bus controlled matching of oscillator tuning voltage to FM
antenna tank circuit tuning voltage
Buffer output for weather band flag
Combined AM and FM IF AGC amplifier with high dynamic input range; one of the four
gain settings is selected automatically via two control signals from IF Digital Signal
Processor (DSP); combined differential AM and FM IF output signal to
analog-to-digital converter of IF DSP
AM mixer for conversion of AM RF to AM IF 10.7 MHz
AM RF PIN diode drive circuit and RF Junction Field Effect Transistor (JFET)
conductance control by AGC cascode drive circuit; AGC threshold detection at AM
mixer and IF AGC input; threshold for detection at AM mixer is programmable via the
I
AM and FM RF AGC monitor output intended for gain control of active antennas
AM up-conversion tuner to an IF frequency of 10.7 MHz for Long Wave (LW)/Medium
Wave (MW)/Short Wave (SW) (31 m, 41 m and 49 m bands)
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 Voltage-Controlled Oscillator (VCO), crystal oscillator and
Phase-Locked Loop (PLL) synthesizer on one chip.
