Free- scale reserves the right to change or discontinue this product without notice HD to SD Adjustable Bandwidth Video Buffer with DC Restore The 34830 is a very high performance video buffer that can handle HDTV bandwidths up to 1080p resolution. The integrated input clamp works with all sync formats and all types of video signals. The 34830 includes an innovative capability to set the bandwidth to the optimum trade-off of performance versus power dissipation. It can be adjusted all the way from HD frequencies to SD frequencies while benefiting from the lower power dissipation with lower bandwidths. The 34830 can drive two standard video loads which are DC or AC coupled. Input signals can be DC or AC coupled. For the DC coupled case, the input sync should be close to ground. The 34830 can be disabled, with shutdown current being 0.12 μA. The 34830 is offered in an ultra thin UDFN package for space critical applications. It operates on a single 3.0 to 5.5V supply over a -40°C to 85°C temperature range.
