Description

Fabricated using the revolutionary, complementary Silicon-Germanium (SiGe) BiCom3X process, the THS7365 is a low-power, single-supply, 2.7-V to 5-V, six-channel integrated video buffer. It incorporates three standard-definition (SDTV) and three high-definition (HDTV) filter channels. All filters feature bypassable sixth-order Butterworth filter characteristics that are useful as digital-to-analog converter (DAC) reconstruction filters or as analog-to-digital converter (ADC) anti-aliasing filters.

The THS7365 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 composite video (CVBS), Y', and R'G'B' signals with sync. AC-coupled biasing for C'/P'B/P'R channels can easily be achieved by adding an external resistor to VS+.

The THS7365 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 per channel, or 75- loads, allows for maximum flexibility as a video line driver. The 20.7-mA total quiescent current at 3.3 V and 0.1 µA (disabled mode) makes it an excellent choice for power-sensitive video applications.

The THS7365 is available in a TSSOP-20 package that is lead-free and green (RoHS-compliant).
