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.
