Hi,
I am using SN75DP159RGZT HDMI driver for HDMI output interface to support 1080p,60fps. I have completed the layout design and did the SI analysis for my board. Attached are the results of insertion and return loss before and after the redriver IC. Before the redriver IC the obtained results for return loss is around -7dB and obtained results of insertion loss is -2dB which is very poor. After the redriver IC the obtained results are in better state. Can the redriver IC accept the signals with low insertion loss of about -2dB and return loss of -7SI_analysis_for HDMI_Out.pdfdB. Are the obtained results valid as per HDMI specification.
