CM2030

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 “low” when no system is connected.

A valid pullup on the HDMI connector pin will overdrive

the internal pulldown and deliver a logic “high” to the

local ASIC.
