Tool/software:
Dear Technical Support Team,
My configuration is HDMI1.4b.
HDMI compliance test result is failed due to VL=approx. 2.5V. The others test are passed.
I changed Vsadj from 6KΩ to 6.49KΩ, but it doesn't work for increasing the level over VL=2.6V.
So I set TERM following and got VL=2.6V.
Current setting is TERM =high(for HDMI2.0) ⇒ VL shows approx. 2.5V
Change TERM =NC(forHDMI1.4b)⇒VL shows approx. 2.6V
Questions:
①Could you show me the reason why VL is increasing for HDMI1.4 with VL=NC?
②Which is better for following configuration?
TMDS_CLOCK_RATIO_STATUS=0 and TERM=NC⇒ no termination(HDMI1.4b) ⇐Current setting VL=2.6V
TMDS_CLOCK_RATIO_STATUS=0 and TERM=L ⇒ 150~300Ω(HDMI1.4b) ⇐ Not yet
Best Regards,
