Digital Radio Modulation/Video Signal Reconstruction

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.

GENERAL DESCRIPTION

The ADV7197 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 ADV7197 outputs analog YPrPb HDTV complying to

EIA-770.3, or RGB complying to RS-170/RS-343A.

The ADV7197 has three separate 10-bit-wide input ports that

accept data in 4:4:4 10-bit YCrCb or RGB, or 4:2:2 10-bit

YCrCb. This data is accepted in HDTV format at 74.25 MHz

or 74.1758 MHz. For any other high definition standard but

SMPTE274M or SMPTE296M, the Async Timing Mode can

be used to input data to the ADV7197. For all standards,

The ADV7197 requires a single 5 V/3.3 V power supply, an

optional external 1.235 V reference, and a 74.25 MHz (or

74.1758 MHz) clock.

The ADV7197 is packaged in a 52-lead MQFP package.
