DESCRIPTIONThe STV6432 is an audio/video output interface for
US STB and DVD.
It adapts in amplitude and impedance the audio
and video signals coming from the digital decoder
to provide them to the TV set, VCR, Auxiliary and
RF modulator.
The video gains are adjustable from 5 dB to 8 dB in
steps of 1 dB.
