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.
