It incorporates three SDTV filters and three selectable SD/ED/HD/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 THS7368 has flexible input coupling capabilities that can be configured for either ac- or dc-coupled inputs. The 300-m V output level shift allows for a full sync dynamic range at the output with 0-V input. The ac-coupled modes include a transparent sync-tip clamp for CVBS, Y', and G'B'R' signals. AC-coupled biasing for C'/P'B/P'R channels can easily be achieved by adding an external resistor to VS+. The THS7368 is an ideal choice for all...
