Application Information
PI3HDMI421AR can be used to re-drive HDMI or DVI signals across internal cables or long FR4 trace
lengths.
If a DTV is designed with a side/front HDMI connector, a separate daughter card is needed for the side/front
HDMI connector and Pericom re-driver.
ATC compliance MUST only be maintained from the front/side connector to the PI3HDMI421AR IC. After
the PI3HDMI421AR signal integrity will be taken care of through the powerful pre-emphasis technique of
the Pericom solution.
