Description
The 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 75 Ω 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).
FEATUREs
■ Y, C, CVBS and RGB inputs with 7 MHz filters
■ 6 dB gains
■ Capabilities of integrated output buffers: single load (150 Ω) for RGB signals double load (75 Ω) 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
