HDMI Subsystem

The HDMI subsystem provides a micro-HDMI* Type-D connector at J10 for connecting compliant displays and HDMI audio devices to the development platform. Refer to Expansion Board Interfaces for the location of the HDMI connector.

The Intel® Joule™ expansion board provides the required filtering and voltage level translation (shifting) between the module HDMI bus and the physical interface outputs.

Refer to the Parade* PS8203 datasheet for the HDMI interface signal specifications.

The required +5 volt power to the micro-HDMI connector is provided directly from the +5 volt boost regulator on the expansion board.
