2 GENERAL DESCRIPTION
The TDA9614H is an audio processing IC for VHS hi-fi and
linear audio, digitally controlled via the I2C-bus. The
FM (de)modulator and peak noise reduction functions are
highly integrated, resulting in few external components
and no external adjustments.
In addition special functions for audio mixing, dubbing and
descrambling have been implemented.
