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 75Ω 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).
