The datasheet of AD8192 says that "The output has a disable feature that places the outputs in tristate mode".
I set HS_EN=0, but the DC voltage(about 2V) seems to appear on TMDS output.
Could you check this?
Hi, If we disable this HS_EN bit,it will go only by standby/low-power mode,So there will be some voltage in TMDS output. The termination resistor should also be disabled for high speed outputs.Please refer page12 in AD8192 datasheet.
Thank you for your reply.
You mean that It is normal that there would be 2V in TMDS outputs of AD8192 when HS_EN and termination resistor are disabled.
So, do you know how the TMDS outputs of AD8192 could be tied to GND when TMDS output is open?
Your cooperation would be great help.
I beleive, if termination resistors also disabled,may be we could not observe any voltage in TMDS output.
Thank you for your cooperation.
Umm...In my customer site, they observed the 2V in TMDS output when the registers was also disabled and TMDS output was open.
Is it possible to check it in your site?
There is separate forum for switchers/Multiplexer group Switches/Multiplexers
Could you please post your question there where you will be more likely to get a knowledgeable answer.
Thank you for your comment.
I have posted this question in switchers/Multiplexer forum.
