Document Number: MC34830
Rev. 1.0, 9/2008
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渭A.
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擄C to
85擄C temperature range.
