AM mixer.
APPLICATIONS
Car radios.
GENERAL DESCRIPTION
The TEA6810V and TEA6811V, together with TEA6821V
forms an AM/FM receiving concept for electronically tuned
car radios.
The TEA681xV is an FM/AM front-end with one local
synthesized oscillator for both AM and FM which is used
together with the TEA6821T in a double-conversion
concept. It delivers a first FM-IF of 72.2 MHz and, for
MW/LW, a first AM-IF of 10.7 MHz.
Minimum alignments are required due to wideband RF
inputs and the common AM/FM VCO.
High dynamic behaviour and minimum distortion is
obtained by a special RF input design combined with AGC.
High sensitivity is possible in combination with RF input
FETs.
Minimum interference is experienced due a to special
synthesizer loop design and ensuring that the I2C-bus is
inoperative in the locked-tuned condition.
The reference frequency for the synthesizer and the
I2C-bus information is delivered by the TEA6821V.
The programmable local/dx switch enables switching the
gain of the FM mixer from normal AGC control (FM dx) to
the forced 4th level of AGC (FM local).
