up resistor.
CEC: HDMI Consumer Electronics Control (CEC) Line. Bidirectional signal, electrical level +3.3V_A with a 27kΩ pull-up resistor and Schottky Diode.
HPD: Hot Plug Detect Input signal. +3.3V_S electrical level signal with 100kΩ pull-down resistor
For ESD protection, on all data and voltage lines are placed clamping diodes for voltage transient suppression.
Always use HDMI-certified cables for the connection between the board and the HDMI display; a category 2 (High-Speed) cable is recommended for higher
resolutions, category 1 cables can be used for 720p resolution.

The Intel Braswell family of SoCs offer three Digital Display Interfaces, configurable to work in
HDMI/DVI/DP++/eDP modes (eDP mode is supported only on DDI #0 and #1).
On the SBC-A80-eNUC board, the Digital Display Interface #0 is used to implement a HDMI
interface.
Therefore, on-board it is available a standard certified HDMI connector, upright,
type A, WIN WIN P/N WHDR-19D1BBNU3N.
Signals involved in HDMI management are the following:
TMDS_CLK+/TMDS_CLK-: TMDS differential Clock.
TMDS_LANE0+/TMDS_LANE0-: TMDS differential pair #0
TMDS_LANE1+/TMDS_LANE1-: TMDS differential pair #1
TMDS_LANE2+/TMDS_LANE2-: TMDS differential pair #2
SDA: DDC Data line for HDMI panel. Bidirectional signal, electrical level +5V
pull-up resistor.
SCL: DDC Clock line for HDMI panel. Output signal, electrical level +5V
