Figure 25. Output-Eye Mask at TTP4
Figure 26. Acceptable Pre-Emphasis Into TMDS361B
Any input pre-emphasis higher than the input condition shown in Figure 26 can result in over-equalization and
potential system failure. During over-equalization, the TMDS361B in the setup of Figure 24 fails the output eye
mask as shown in Figure 25.
