Hotplug Detect Logic
The CM2030 ensures that the local ASIC will properly detect an HDMI compliant Sink. The current sink main-
tains a local logic âlowâ when no system is connected.
A valid pullup on the HDMI connector pin will overdrive the internal pulldown and deliver a logic âhighâ to the
local ASIC.
