Features
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 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).
April 2009
Y, C, CVBS inputs with 7 MHz filters
Y, Pr, Pb inputs with 14 MHz filters
6 dB gains
Capabilities of integrated output buffers: single
load (150 ) for Y/Pr/Pb signals
double load (75 ) for Y, C and CVBS signals
DC coupled outputs for CVBS and YPrPb
signals, DC or AC coupled output for chroma
signal
Bottom clamp on Y and CVBS, bias clamp on
C, sync clamps on Pr and Pb
Crosstalk: 55 dB (typ.)
Separate stand-by modes on Y/C/CVBS and
on Y/Pr/Pb signals
Switchable Y+C adder for decoders without
CVBS outputs
Filtered video buffers for STB and DVD devices
