Circuit Description
The TUA 4310X has been designed as integrated tuner with strictly symmetrical
RF-parts for use in car radios. In addition the IC provides a prestage control and an IF
post amplification.
The IC is especially suitable for use in car radios with prestage control and distributed
IF-selection.
The integrated circuit includes an 2-pin oscillator with symmetrical input, buffered output
and a double balanced mixer for frequency conversion. The RF-input stage allows
symmetrical and unsymmetrical operation. The resulting IF is amplified in a first linear
IF-driver with adjustable gain and in a second IF-driver with an adjustable temperature
coefficient. Between these drivers an additional IF-selection is recommended. The
AGC-stage integrated for prestage control can drive PIN-Diodes as well as MOSFET’s.
The IC also includes a reference voltage source with high supply voltage ripple rejection.
