GENERAL DESCRIPTION
The TDA9610H is a dual audio FM processing IC for VHS
hi-fi 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 adjustments.
In addition special functions for audio editing, mixing and
dubbing have been implemented.
