TI THS7364六路低功耗HD(SD)视频解决方案

TI 公司的THS7364是采用SiGe BiCom3X工艺的六路低功耗HD(SD)视频缓冲器,集成了三个SDTV滤波器(9.5-MHz)和三个全HD的HDTV滤波器(72-MHz),所有滤波器具有可旁通的6阶Butterworth特性, 内置增益6-dB (2 V/V) ,单电源+2.7V 到+5V工作,主要用在STB,PVR/DVDR和BluRay输出视频缓冲器.本文介绍了THS7364主要特性,功能方框图,多种应用电路图以及THS7364EVM评估板主要特性,电路图,材料清单和PCB布局图.

Fabricated using the revolutionary, complementary Silicon-Germanium (SiGe) BiCom3X process, the THS7364 is a low-power, single-supply, 2.7-V to 5-V, six-channel integrated video buffer. It incorporates three SDTV filters and three Full-HD (also known as True-HD) HDTV filters. All filters feature bypassable sixth-order Butterworth characteristics that are useful as digital-to-analog converter (DAC) reconstruction filters or as analog-to-digital converter (ADC) anti-aliasing filters.

The THS7364 has flexible input coupling capabilities, and can be configured for either ac- or dc-coupled inputs. The 300-mV output level shift allows for a full sync dynamic range at the output with 0-V input. AC-coupled modes include a transparent sync-tip clamp for CVBS, Y’, and G’B’R’ signals.
