GENERAL DESCRIPTION The ADV7302A/ADV7303A is a high speed, digital-to-analog encoder on a single monolithic chip. It includes six high speed video D/A converters with TTL compatible inputs. The ADV7302A/ADV7303A has three separate 8-bit wide input ports that accept data in high definition and/or standard definition video format. For all standards, external horizontal, vertical, and blanking signals, or EAV/SAV timing codes, control the insertion of appropriate synchronization signals into the digital data stream and therefore the output signals. FEATURES High Definition Input Formats YCrCb Compliant to SMPTE293M (525 p), ITU-R.BT1358 (625 p), SMPTE274M (1080 i), SMPTE296M (720 p), and Any Other High Definition Standard Using Async Timing Mode RGB in 3 x 8-Bit 4:4:4 Format BTA T-1004 EDTV2 525 p Parallel High Definition Output Formats (525 p/625 p/720 p/1080 i) YPrPb Progressive Scan (EIA-770.1, EIA-770.2) YPrPb HDTV (EIA 770.3) RGB + H/V (HDTV 5-Wire Format) CGMS-A (720 p/1080 i) Macrovision Rev 1.0 (525 p/625 p)* CGMS-A (525 p) Standard Definition Input Formats CCIR-656 4:2:2 8-Bit Parallel Input CCIR-601 4:2:2 16-Bit Parallel Input Standard Definition Output Formats Composite NTSC M, N; PAL M, N, B, D, G, H, I, PAL-60 SMPTE170M NTSC Compatible Composite Video ITU-R.BT470 PAL Compatible Composite Video S-Video (Y/C) EuroScart RGB Component YUV (Betacam, MII, SMPTE/EBU N10) Macrovision Rev 7.1* CGMS/WSS Closed Captioning GENERAL FEATURES Simultaneous SD and HD Inputs and Outputs Oversampling (108 MHz/148.5 MHz) On-Board Voltage Reference 6 Precision Video 11-Bit DACs 2-Wire Serial MPU Interface Dual I/O Supply 2.5 V/3.3 V Operation Analog and Digital Supply 2.5 V On-Board PLL 64-LQFP Package Lead-Free Product APPLICATIONS DVD Players SD/HD Display Devices SD/HD Set-Top Boxes SD/HDTV Studio Equipment
