chiu wesley said: FPGA input requires to be AC coupled, but TMDS181 output needs to be 3.3V common mode voltage, so use external 50ohm termination to 3.3V to set the CM. But 50ohm termination and FGPA input termination create double termination so output…
Part Number: TMDS181 Hello,
I have developed HDMI in interface to Zynq ultrascale+ FPGA through TMDS181 chip.
It does not share EDID information. Source is a Laptop. When we probe DDC signals they keep remain high all the time when HDMI cable is connected…

Hello, Jeevan,
You can check that there good isolation on your HPD pin from any of your power planes or pins.
What you are seeing is not expected since expected behavior is as follows:
Without any device connected to J28:
HPD_SRC measures 0 V
HPD_SNK…

Hi,
1. Customer wants to use TMDS181 as input side (source). The TMDS181 receives AC-coupled signals, but could you please tell me a reference circuit or precautions for…
Part Number: TMDS181 Hi Team,
TMDS181 is used in our product.
The ACTIVE DDC BLOCK wants to be set to the snoop option.
SCL_SNK/SDA_SNK is connected to the DDC of SRC and SNK to implement the snoop function.
Do I understand it correctly?
What is the purpose…
