| (R) STV6433 Filtered Video Buffers for STB and DVD Devices TARGET SPECIFICATION FEATURES s Y, C Inputs with 7.1 MHz filters s 40 dB Stop Band Attenuation at 27 MHz s RF Signal with 14 dB Notch Filter at 4.5 MHz for Sound Trap s RF Signal with -170 ns Differential Group Delay between 400 kHz and 3.58 MHz s 6 dB Gain s Capabilities of Integrated Output Buffers: Double-adapted Loads (75) on CVBS Output, Single-adapted Loads on Y and C Outputs s AC-coupled Inputs s DC-coupled Outputs for Y, CVBS and RFOUT s DC- or AC-coupled Output for COUT s Bottom Clamp on Y, Bias Clamp on C s Crosstalk: 55 dB (typical) SO8 Order Code: STV6433 DESCRIPTION The 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. September 2003 This is preliminary information on a new product now in development or undergoing evaluation.
