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

Ω

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).
