STV6433 Filtered Video Buffers

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 a.
