DESCRIPTION
The STV6436 is a filtered video output interface for
STB and DVD applications.
After removing D/A conversion noises using
integrated low pass filters, the STV6436 adapts in
amplitude and impedance the video signals coming
from the digital decoder for transmission, via 75Ω
adapted cables, to the TV set, VCR and auxiliary
devices.
The STV6436 is powered by a 5V supply.
The STV6436 is fully compatible with STi55xx
Digital Decoders.
The STV6436 is mounted in a SO24 package
(STV6436S) or in a DIP package (STV6436D).
