Overview

Six 11-bit DACs for mutiple video outputs

2x, 4x & 8x Oversampling for High-Definition, Progressive Scan and Standard Definition Video

The ADV7303A is a digital-to-analog encoder for Standard Definition and/or High Definition [525p, 625p, 1080i, 720p, etc] video from Analog Devices.

The ADV7303A converts any 8-bit YCrCb High Definition and/or Standard Definition Video in NTSC, PAL [B, D, G, H, I, M, N, PAL-60] into YPrPb or RGB analog component High Definition video and/or Standard Definition CVBS, S-Video, YUV or RGB component video. It is also possible to input High Definition RGB data in 4:4:4 format, outputs being RS170 and RS343A compatible.

Component High Definition video outputs are compatible with EIA770.1, EIA770.2 and EIA770.3. Standard Definition supports YUV BetaCam, MII, SMPTE/EBU N10, SMPTE 170M NTSC and ITU-R.BT 470 PAL output formats.

The ADV7303A consists of six 11-Bit DACs.

Oversampled outputs are available for Standard Definition [8x at 108 MHz], Progressive Scan [4x at 108 MHz], and HDTV [2x at 148.5 MHz].

Programmable features include a test pattern generator for HD and SD, YCrCb to RGB matrix, Gamma Correction, Adaptive Filter Control, Sharpness Filter Control, Digital Noise Reduction, multiple Luma and Chroma filters for SD, Luma SSAF with programmable gain/attenuation, separate Pedestal on component and CVBS/S-Video, VBI, an Undershoot Limiter, Color Control.

The ADV7303A provides CGMS-A [HD], CGMS/WSS [SD], Closed Captioning [SD].

The ADV7303A modes are set up over a serial bi-directional I²C port.

The ADV7303A is packaged in a 64-pin LQFP and requires a dual supply voltage of 2.5 V for the Analog and Digital Supply and 2.5 V/3.3 V for I/O supply.
