THS7303

The THS7303 is a low-power, single-supply 2.7-V to 5-V, 3-channel integrated video buffer, fabricated using the new complimentary silicon-germanium (SiGe) BiCom-III process. It incorporates a selectable 5th order Buttenrvorth filter to eliminate data converter images. Each channel of the THS7303 is individually l2C configurable for all functions which makes it flexible for any application. Its rail-to-rail output stage allows for both ac and dc coupling applications. The 6-dB gain along with the built-in SAG correction allows for maximum flexibility as an output video buffer. The 9-MHz is a perfect choice for SDTV video including composite S-Video, and 480i/576i Y'P'BP'R, and (R'G'B') signals. The 16-MHz filter is ideal for EDTV 480p/576p Y'P'BP'R, and VGA signals. The 35-MHz filter is useful for HDTV 720p/1080i Y'P'BP'R, and SVGAIXGA signals. For 1080p or SXGA/UXGA signals, the filter can be bypassed allowing a 190-MHz bandwidth, 300-V/us amplifier to buffer the signal. The 16.6-mA total quiescent current (55 mW total power) makes the THS7303 an excellent choice for USB powered or portable video applications. While fully disabled, the THS7303 consumes only 0.1A making it ideal for energy sensitive applications.
