TARGET SPECIFICATION
STV6435Filtered Video Buffers for STB and DVD Devices
FEA TURES Y, C, CVBS and RGB Inputs with 7 MHz Filters6 dB Gains Capabilities of Integrated Output Buffers:
Single Load (150Ω) for RGB signals
Double Load (75Ω) for Y, C and CVBS signals DC Coupled Outputs for CVBS and RGB
signals, DC or AC coupled output for Chroma
signal Bottom Clamp on RGB, Y and CVBS, Bias
Clamp on C Crosstalk: 55 dB (typ.) Separate Stand-by Modes on Y/C/CVBS and
on RGB signals Switchable Y+C Adder for Decoders without
CVBS Outputs
DESCRIPTIONThe STV6435 is a filtered video output interface for
STB and DVD applications.
After removing D/A conversion noises using
integrated low pass filters, the STV6435 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 STV6435 is powered by a 5V supply.
The STV6435 is fully compatible with STi55xx
Digital Decoders.
The STV6435 is mounted in a SO24 package
(STV6435S) or in a DIP package (STV6435D).

STV6435 General Information General Information Note: The three RGB channels are identical and their pin assignments may be interchanged in an
application if needed. In this case, verify that the outputs correspond to the inputs; for example, the
pin 7 input must correspond to the pin 14 output.
