29

SDA_SINK

I/O

5V DDC Data I/O. Pulled up by external termination to 5V. Con-

nected to SDA_SOURCE through voltage limiting integrated

NMOS passgate.

30

HPD_SINK

I

Low Frequency, 0V to 5V (nominal) input signal. This signal comes

from the TMDS connector. Voltage High indicates “plugged” state;

voltage low indicated “unplugged”. HPD_SINK is pulled down by

an integrated 100K ohm pull-down resistor.

32

DDC_EN

I

Enables bias voltage to the DDC passgate level shifter gates. (May

be implemented as a bias voltage connection to the DDC pass gates

themselves.)

38

IN_D1-

I

Low-swing diff input from DP Tx outputs. IN_D1- makes a differ-

ential pair with IN_D1+.

39

IN_D1+

I

Low-swing diff input from DP Tx outputs. IN_D1+ makes a dif-

ferential pair with IN_D1-.

41

IN_D2-

I

Low-swing diff input from DP Tx outputs. IN_D2- makes a differ-

ential pair with IN_D2+.

42

IN_D2+

I

Low-swing diff input from DP Tx outputs. IN_D2+ makes a dif-

ferential pair with IN_D2-.

44

IN_D3-

I

Low-swing diff input from DP Tx outputs. IN_D3- makes a differ-

ential pair with IN_D3+.

45

IN_D3+

I

Low-swing diff input from DP Tx outputs. IN_D3+ makes a dif-

ferential pair with IN_D3-.

47

IN_D4-

I

Low-swing diff input from DP Tx outputs. IN_D4- makes a differ-

ential pair with IN_D4+.

48

IN_D4+

I

Low-swing diff input from DP Tx outputs. IN_D4+ makes a dif-

ferential pair with IN_D4-.
