TARGET SPECIFICATION
STV6433Filtered Video Buffers for STB and DVD Devices
FEA TURES Y, C Inputs with 7.1 MHz filters 40 dB Stop Band Attenuation at 27 MHz RF Signal with 14 dB Notch Filter at 4.5 MHz
for Sound Trap RF Signal with -170 ns Differential Group
Delay between 400 kHz and 3.58 MHz6 dB Gain Capabilities of Integrated Output Buffers:
Double-adapted Loads (75Ω) on CVBS
Output, Single-adapted Loads on Y and C
Outputs AC-coupled Inputs DC-coupled Outputs for Y, CVBS and RFOUT DC- or AC-coupled Output for COUT Bottom Clamp on Y, Bias Clamp on C Crosstalk: 55 dB (typical)
DESCRIPTIONThe STV6433 is a filtered video output interface for DVD, Satellite and Cable Set-Top Box applications.
After removing D/A conversion noise using integrated low pass filters, the STV6433 adapts the Y and C
signals coming from the digital decoder in amplitude and impedance for transmission to the TV set and an
auxiliary device (VCR, DVD recorders, etc.) via adapted 75-ohm cables.
A Y+C adder with buffer for providing a CVBS signal to external loads and a pre-processing of a CVBS
signal for RF modulator (RFOUT) are included in STV6433.
This pre-processing is a notch filtering at 4.5 MHz (before the addition of the audio signal in the RF
modulator) and a 170 ns Y/C delay (to compensate the nominal distorsion in the TV IF filter).
The STV6433 is powered by a 5V voltage supply and is fully-compatible with STi55xx digital encoders.
