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).
HPDET I
Hot Plug Detect (internal pull-down):
This input pin determines
whether the DVI is connected to a DVI monitor. When terminated,
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.
TMDSDATA
I/O
DVO I2C Data:
This signal is used as the I2C_DATA for a digital
display (i.e. TV-Out Encoder, TMDS transmitter). This signal is
tri-stated during a hard reset.
TMDSDCLK I/O
DVI DDC Clock:
This signal is used as the DDC clock for a digital
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.
