STV6435

Filtered video buffers for STB and DVD devices

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)

t(s for Y, C and CVBS signals

c ■ DC coupled outputs for CVBS and RGB

du signals, DC or AC coupled output for Chroma

ro ) signal

P t(s ■ Bottom clamp on RGB, Y and CVBS, bias

te c clamp on C

le u ■ Crosstalk: 55 dB (typ.)

so rod ■ Separate stand-by modes on Y/C/CVBS and

on RGB signals

- Ob te P ■ Switchable Y+C adder for decoders without

CVBS outputs

t(s) sole Description

uc Ob The STV6435 is a filtered video output interface

d - for STB and DVD applications.

Pro t(s) After removing D/A conversion noises using

integrated low pass filters, the STV6435 adapts in

te c amplitude and impedance the video signals

le u coming from the digital decoder for transmission,

so rod via 75 Ω adapted cables, to the TV set, VCR and

auxiliary devices.

Ob te P The STV6435 is powered by a 5V supply.

le The STV6435 is fully compatible with STi55xx

o digital decoders.

bs The STV6435 is mounted in a SO24 package

O(STV6435S).
