AD7400A,pdf datasheet (Multifo

The ADV7181B integrated video decoder automatically detects
and converts a standard analog baseband television signal
compatible with worldwide standards NTSC, PAL, and SECAM
into 4:2:2 component video data compatible with 16-bit/8-bit
CCIR601/CCIR656.
The advanced, highly flexible digital output interface enables
performance video decoding and conversion in line-locked
clock-based systems. This makes the device ideally suited for a
broad range of applications with diverse analog video characteristics,
including tape-based sources, broadcast sources,
security/surveillance cameras, and professional systems.
The six analog input channels accept standard composite,
S-Video, and YPrPb video signals in an extensive number of
combinations. AGC and clamp restore circuitry allow an input
video signal peak-to-peak range of 0.5 V to 1.6 V. Alternatively,
these can be bypassed for manual settings.
