Hi,

Is the capacitor and 499 Ohms resistors in HDMI data lines a must? I'm not able to see the display on the HDMI screen. So getting doubt. Could you please suggest solutions?

Hi,

Is it a HDMI sending device or a HDMI receiving device?
Where is the schematic from?

It's a transmitter.
The schematics are from a company I work for.

According to shown connections of certain signals, e.g. HPD, this is a HDMI source device (transmitter). Also the signal names HDMI_TXxx suggest the same.

The circuit is implementing the AC coupled HDMI TX scheme. You should refer to the transmitter spec to understand why it's used.

As a first step, you should clarify about RX or TX function.

Hi, It's a transmitter. Any information to make it work will be helpful.
Sorry for the wrong information earlier.

what is the RX and the TX functions in your schematic? That is the first thing you should specify. Do you have the schematic file I try to troubleshoot it for you?
