HD to SD Adjustable Bandwidth

Video Buffer with DC Restore

34830

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 0.12μA.

EP SUFFIX (PB-FREE)

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.
