GENERAL DESCRIPTION
The ADV7199 is 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 ADV7199 supports CGMS-A data control generation
and the Macrovision Anticopy algorithm in 525p mode.
The ADV7199 is packaged in a 52-Pin MQFP package.
The ADV7199 has three separate 8-Bit wide input ports
which accept data in 4:4:4 8-Bit YCrCb or RGB or 4:2:2
8-Bit YCrCb. This data is accepted in progressive scan
format at 27MHz or HDTV format at 74.25MHZ or
74.1758MHz. 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 ADV7199. For all standards, external
horizontal, vertical and blanking signals or EAV/SAV
codes control the insertion of appropriate synchronisation
signals into the digital data stream and therefore the
output signals.
