Fabricated using the revolutionary, complementary Silicon-Germanium (SiGe) BiCom3X process, the THS7360 is a low-power, single-supply, 2.7-V to 5-V, six-channel integrated video buffer. It incorporates three SDTV filter channels and three selectable filter (SF) channels with SD/ED/HD/Full-HD (also known as True-HD) HDTV filtering. All filters feature 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 THS7360 also has flexible input coupling capabilities that can be configured for either ac- or dc-coupled inputs. The 120-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 option 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 THS7360 is an ideal choice for all video buffer applications. Its rail-to-rail output stage with 5.6-V/V gain (for SD channels) and 4.5-V/V gain (for SF channels) 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 24.5-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 THS7360 is available in a TSSOP-20 package that is lead-free and green (RoHS-compliant).
