TDP0604: Can it be used with 1.8V HDMI input?

Roy Hsu

Part Number: TDP0604

Hi Team,

Can the TDP0604 be used with 1.8V HDMI input? It has an internal 3.3V voltage bias so I think an 1.8V input probably won't comply with it. If so, do we have any HDMI redrivers/retimers that can accept 1.8V input signals?

Thanks!

Do you have more detail on this 1.8V requirement?

The TDP0604 supports 1.2-V, 1.8-V, and 3.3-V LVCMOS levels. The VIO pin is used to select which voltage level is used for the following 2-level control pins: LV_DDC_SDA, LV_DDC_SCL, SCL/CFG0, and SDA/CFG1.

Thanks

David

Hi David,

I was not referring to the low-speed I/Os but the main link input signals. I'm looking for a redriver/retimer which can support 1.8V main-link signals so that it can be used with the MCU of interest.

Thanks!

Do you have the actual DC electrical characteristic data for the HDMI output or a connection block diagram that you can share? I am trying to understand where this 1.8V requirement comes from since HDMI is a 3.3V DC-coupled interface.

Thanks
