THS7368

具有 3-SD 和 3-SD/ED/HD/全高清滤波器和 6dB 增益的 6 通道视频放大器

Fabricated using the revolutionary, complementary Silicon-Germanium SiGe BiCom3X process, the is a low-power, single-supply, 2.7-V to 5-V, six-channel integrated video buffer. 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-mV 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 video buffer applications. Its rail-to-rail output stage with 6-dB gain allows for both ac and dc line driving. The ability to drive two lines, or 75- loads, allows for maximum flexibility as a video line driver. The 23.4-mA total quiescent current at 3.3 V and 0.1 µA disabled mode makes it a good choice for systems that must meet power-sensitive Energy Star standards.

The THS7368 is available in a TSSOP-20 package that is lead-free and green RoHS-compliant.
