*********************************** Displayport Mode **************************************
(1) Link Rate (auto=0, 162G=1, 2.7G=2)
Auto : Signal generator connected with the DP display device has a unique value of the
DPCD to check the entry of the “Link Rate” for the automatic output mode
1. 62G : This output mode that DP display unit has to ignore the value of DPCD and
output by link rate fixed to 1.62GB.
2. 7G : This output mode that DP display unit has to ignore the value of DPCD and output
by link rate fixed to 2.7GB.
(2) Lane Count (auto=0,1=1, 2=2, 4=3)
Auto : DP display device has a unique value of the DPCD to check the entry of the “Lane
Count” for the automatic output mode.
1Lane : The mode, using the 1Lane of DP display to output data.
2Lane : The mode, using the 2Lane of DP display to output data.
4Lane : The mode, using the 4Lane of DP display to output data.
Link rate = 2.7 Gbps
- 1 lane = 270 Mbytes per second
- 2 lane = 540 Mbytes per second
- 4 lane = 1080 Mbytes per second
Link rate = 1.62 Gbps
- 1 lane = 162 Mbytes per second
- 2 lane = 324 Mbytes per second
- 4 lane = 648 Mbytes per second
(3) Down Spread (auto=0, 0%=1, 0.5%=2) : SSC Range Measurement
Auto : DP display device has a unique value of the DPCD to check the entry of the “Down
Spread” for the automatic output mode
0% : “Down Spread Amplitude 0%” to output mode(SSC Disable Mode)
0.5% : “Down Spread Amplitude 0.5%” to output mode(SSC Disable Mode)
SSC(Spread Spectrum Clocking)
:A technique used to reduce electromagnetic interference (EMI) produced by synchronous
digital systems (such as computer systems).
(4) p-to-p (0.4=0 ,0.6=1, 0.8=2, 1.2=3) : Variable test output level
0.4 : The signal from DP port output level 0.4Vp-p to the output by setting the mode.
0.6 : The signal from DP port output level 0.6Vp-p to the output by setting the mode.
0.8 : The signal from DP port output level 0.8Vp-p to the output by setting the mode.
1.2 : The signal from DP port output level 1.2Vp-p to the output by setting the mode.
