NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
2Analog Output Short Circuit to any Power Supply or Common can be of an indefinite duration.
DescriptionThe 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.
