Functional Description
FM-IF amplifier, consisting in a limiter amplifier with FM demodulator. The AF section contains a
SCART-record/playback switch as well as AF output with volume control. The control of the volume
is controlled via an analog control input, and the SCART switch is controlled via a switch input.
Application
Application of the IC is intended in mono TV sets.
Circuit Description
In its FM section, the component contains an eight stage, symmetrical limiter amplifier with
subsequent coincidence demodulator. The AF section contains an analog switch for the SCART-
recording / playback function as well as an analog volume control with AF output.
