6 14-bit NSV Precision Video™ DACs for ultra-high-end video generation

Advanced Sigma-Delta DACs Provide Noise Shaped Video™ Output
108MHz Oversampling for
Standard Definition

The ADV7305A is a digital to analog encoder for Standard Definition and/or High Definition [525p, 625p, 1080i, 720p, etc] video from Analog Devices.

The ADV7305A converts any 10-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 ADV7305A consists of six NSV™ 14-Bit Sigma-Delta DACs. Oversampled outputs are available for Standard Definition [8x at 108MHz], 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 ADV7305A provides CGMS-A [HD], CGMS/WSS [SD], Closed Captioning [SD].

The ADV7305A modes are set up over a serial bi-directional I²C port.

The ADV7305A is packaged in a 64-pin LQFP and requires a dual supply voltage of 2.5V for the Analog and Digital Supply and 2.5/3.3V for I/O supply.
