Texas Instruments  THS7327PHP

Fabricated using the new complementary silicon-germanium (SiGe) BiCom-III process, the THS7327 is a low-power, single-supply 2.7-V to 5-V, 3-channel integrated video buffer with H and V Sync signal paths. It incorporates a selectable 5th order Butterworth anti-aliasing filter on each channel. The 9-MHz is a perfect choice for SDTV video including composite, S-Video™, and 480i/576i. The 16-MHz filter is ideal for EDTV 480p/576p and VGA signals. The 35-MHz filter is useful for HDTV 720p/1080i and SVGA signals. The 75-MHz filter is ideal for HDTV 1080p and XGA/SXGA signals. For UXGA/QXGA R’G’B’ signals, the filter can be bypassed allowing a 500-MHz bandwidth, 1150-V/µs amplifier to buffer the signal.
