(1) Stresses above those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied Exposure to absolute maximum rated conditions for extended periods may degrade device reliability.
(2) The absolute maximum junction temperature under any condition is limited by the constraints of the silicon process.
(3) The absolute maximum junction temperature for continuous operation is limited by the package constraints. Operation above this temperature may result in reduced reliability and/or lifetime of the device.
DescriptionFabricated using the new complimentary 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. THS7327 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 THS7327 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/ms amplifier to buffer the signal.
