Quote-san,
Thank you for your replay.
Our system is receiver system with TMDS361B. Souse system (ex: PC) monitor is not only HDP(Hot Pllug Detect) but also TMDS signal level to judge connected Souse system and Receiver system.
If it uses Clock-detect…
Other Parts Discussed in Thread: TMDS361B Hi
We want to find the following information. If you have the answer, could you show us?
Device:TMDS361B 1. Do you have the impedance value for following inputs? (Pin 4, 5, 38 39, 53, 54 TMDS_CLK input)
…
Other Parts Discussed in Thread: TMDS361B Hello all,
I have gone through the datasheet , but the comment in datasheet is creating doubt about this chip/IC "TMDS361B is not intended for source side applications such as external switch boxes" Could you…
Hi Kawai-san,
Having a long cable will increase rise/fall time, this is because you have resistance/capacitor circuit, the long cable will increase circuit resistance leading to longer time to charge/discharge the capacitor, that's why I²C specification…
Hi Kawai-san,
I think the reason for this shorter time may be differences in production yield variance or even materials.
Having values outside of range are not critical, when Tphl or Tplh aproaches zero, it means the signal is propagating similar…
Thanks Elias,
I've posted a couple scope pictures. They are not the best. I only have a 1Ghz scope.
The issue only occurs at higher resolutions, 148.5Mhz clock. We only operate at two frequencies. It seems to work fine at 74.25Mhz.
I failed to…
Hello Kawai,
I've been looking into this and I have the answer:
The HDMI Compliance test specifies for "TMDS Termination Voltage" test that the source must be disconnected from the sink in order to measure the voltage at the TMDS lines.
The clock…
Hello Kawai,
First of all, your assumptions seems to indicate the the device has some kind of problems passing compliance test, the TMDS361B has no issues passing the "tmds voltage termination" compliance test when you apply a valid clock input or when…
