Signal Pin # Description
DDI3_PAIR1+ C42 Multiplexed with DP3_LANE1+ and TMDS3_DATA1+
DDI3_PAIR1- C43 Multiplexed with DP3_LANE1- and TMDS3_DATA1-
DDI3_PAIR2+ C46 Multiplexed with DP3_LANE2+ and TMDS3_DATA0+
DDI3_PAIR2- C47 Multiplexed with DP3_LANE2- and TMDS3_DATA0-
DDI3_PAIR3+ C49 Multiplexed with DP3_LANE3+ and TMDS3_CLK+
DDI3_PAIR3- C50 Multiplexed with DP3_LANE3- and TMDS3_CLK-
DDI3_HPD C44 Multiplexed with DP3_HPD and HDMI3_HPD
DDI3_CTRLCLK_AUX+ C36 Multiplexed with DP3_AUX+ and HDMI3_CTRLCLK
DP AUX+ function if DDI3_DDC_AUX_SEL is no connect
HDMI/DVI I2C CTRLCLK if DDI3_DDC_AUX_SEL is pulled high
DDI3_CTRLDATA_AUX- C37 Multiplexed with DP3_AUX- and HDMI3_CTRLDATA
DP AUX- function if DDI3_DDC_AUX_SEL is no connect
HDMI/DVI I2C CTRLDATA if DDI3_DDC_AUX_SEL is pulled high
DDI3_DDC_AUX_SEL C38 Selects the function of DDI3_CTRLCLK_AUX+ and DDI3_CTRLDATA_AUX-
This pin shall have a 1 M pull-down to logic ground on the module. If this
input is floating, the AUX pair is used for the DP AUX+/- signals. If pulled-
high, the AUX pair contains the CTRLCLK and CTRLDATA signals.
Note
The DDI interfaces support dual-mode DisplayPort. To support TMDS, an external level shifter (PTN3360D) should be implemented on the
user's carrier board.
