ADV7342

ADV7342 概要

GENERAL DESCRIPTIONThe ADV7342/ADV7343 are high speed, digital-to-analog video encoders in a 64-lead LQFP package. Six high speed, 3.3 V, 11-bit video DACs provide support for composite (CVBS), S Video (Y/C), and component (YPrPb/RGB) analog outputs in either standard definition (SD), enhanced definition (ED), or high definition (HD) video formats.The ADV7342/ADV7343 each have a 24-bit pixel input port that can be configured in a variety of ways. SD video formats are supported over a SDR interface and ED/HD video formats are supported over SDR and DDR interfaces. Pixel data can be supplied in either the YCrCb or RGB color spaces.FEATURES74.25 MHz 20-/30-bit high definition input support   Compliant with SMPTE 274M (1080i), 296M (720p), and 240M (1035i)6, 11-bit, 297 MHz video DACs   16× (216 MHz) DAC oversampling for SD   8× (216 MHz) DAC oversampling for ED   4× (297 MHz) DAC oversampling for HD   37 mA maximum DAC output currentNTSC M, PAL B/D/G/H/I/M/N, PAL 60 supportNTSC and PAL square pixel operation (24.54 MHz/29.5 MHz)Multiformat video input support   4:2:2 YCrCb (SD, ED, and HD)   4:4:4 YCrCb (ED and HD)   4:4:4 RGB (SD, ED, and HD)Multiformat video output support   Composite (CVBS) and S-Video (Y/C)   Component YPrPb (SD, ED, and HD)   Component RGB (SD, ED, and HD)Macrovision® Rev 7.1.L1 (SD) and Rev 1.2 (ED) compliantSimultaneous SD and ED/HD operationEIA/CEA-861B compliance supportProgrammable features   Luma and chroma filter responses   Vertical blanking interval (VBI)   Subcarrier frequency (FSC) and phase   Luma delayCopy generation management system (CGMS)Closed captioning and wide screen signaling (WSS)Integrated subcarrier locking to external video sourceComplete on-chip video timing generatorOn-chip test pattern generationOn-board voltage reference (optional external input)Serial MPU interface with dual I2C® and SPI® compatibility3.3 V analog operation1.8 V digital operation3.3 V I/O operationTemperature range: −40°C to +85°CAPPLICATIONS  DVD recorders and players  High definition Blu-ray DVD players  HD-DVD players
