ADV7195

The ADV7195 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 ADV7195 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 progressive scan format at 27 MHz or HDTV format at 74.25 MHz or 74.1758 MHz. For any other high-definition standard but SMPTE293M, ITU-R BT.1358, SMPTE274M or SMPTE296M the Async Timing Mode can be used to input data to the ADV7195. 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 ADV7195 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 ADV7195 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 ADV7195 supports CGMS-A data control generation.

The ADV7195 is packaged in a 52-lead MQFP package.
