GENERAL DESCRIPTION
The ADV7196A is a triple high-speed, digital-to-analog encoder
on a single monolithic chip. It consists of three high-speed video
D/A converters with TTL-compatible inputs.
The ADV7196A has three separate 10-bit-wide input ports which
accept data in 4:4:4 10-bit YCrCb or RGB or 4:2:2 10-bit YCrCb.
This data is accepted in progressive scan format at 27 MHz or
HDTV format at 74.25 MHz or 74.1758 MHz. For any other
high-definition standard but SMPTE 293M, ITU-R BT.1358,
SMPTE274M or SMPTE296M the Async Timing Mode can be
used to input data to the ADV7196A. For all standards, external
horizontal, vertical, and blanking signals or EAV/SAV codes control
the insertion of appropriate synchronization signals into the digital
data stream and therefore the output signals.
The ADV7196A outputs analog YPrPb progressive scan format
complying to EIA-770.1, EIA-770.2; YPrPb HDTV complying
to EIA-770.3; RGB complying to RS-170/RS-343A.
The ADV7196A requires a single 3.3 V power supply, an
optional external 1.235 V reference and a 27 MHz clock in
Progressive Scan Mode or a 74.25 MHz (or 74.1758 MHz)
clock in HDTV mode.
In Progressive Scan Mode, a sharpness filter with programmable
gain allows high-frequency enhancement on the luminance signal.
Programmable Adaptive Filter Control, which may be used, allows
removal of ringing on the incoming Y data. The ADV7196A
supports CGMS-A data control generation and the Macrovision
Anticopy algorithm in 525p mode.
The ADV7196A is packaged in a 52-lead MQFP package.
