2.4.26.1 Signal Description – TMDS Connecter (JTMDS1)

Signal	Type	Signal Description
TDC0, TDC0#	O	DVI Data Channel 0 Outputs: These pins provide the DVI differential
		outputs for data channel 0 (blue).
TDC1, TDC1#	O	DVI Data Channel 1 Outputs: These pins provide the DVI differential
		outputs for data channel 1 (green).
TDC2, TDC2#	O	DVI Data Channel 2 Outputs: These pins provide the DVI differential
		outputs for data channel 2 (red).
		Hot Plug Detect (internal pull-down): This input pin determines
		whether the DVI is connected to a DVI monitor. When terminated,
HPDET	I	the monitor is required to apply a voltage greater than 2.4 volts.
		Changes on the status of this pin will be relayed to the graphics
		controller via the P-OUT/TLDET* or GPIO (1)/TLDET* pin pulling low.
		DVO I2C Data: This signal is used as the I2C_DATA for a digital
TMDSDATA	I/O	display (i.e. TV-Out Encoder, TMDS transmitter). This signal is
		tri-stated during a hard reset.
		DVI DDC Clock: This signal is used as the DDC clock for a digital
TMDSDCLK	I/O	display connector (i.e. primary digital monitor). This signal is tri-stated
		during a hard reset.
TLC, TLC#	O	DVI Clock Outputs: These pins provide the differential clock outputs
		for the DVI interface corresponding to data on TDC (0:2) outputs.
