DESCRIPTION
The STV6434 is a filtered video output interface for
STB and DVD applications.
After removing D/A conversion noises using
integrated low pass filters, the STV6434 adapts in
amplitude and impedance the video signals coming
from the digital decoder for transmission, via 75鈩?/div>
adapted cables, to the TV set, VCR and auxiliary
devices.
The STV6434 is powered by a 5V supply.
The STV6434 is fully compatible with STi55xx
Digital Decoders.
The STV6434 is mounted in a SO24 package
(STV6434S) or in a DIP package (STV6434D).
