TDA2PSX-ACD: TDA2P-ACD HDMI pinmux issues.

H-J

Part Number: TDA2PSX-ACD

Hello，

When I used TI PinMux Tool to allocate the pins of HDMI, I encountered an error "voltage conflict".
I want vdda_hdmi= 1.8v (differential clock and data), Vddshv3= 3.3v (CEC, HPD, SCL, SDA signal is 3.3v), how should I configure?
Attached is my pinmux file.
TI PinMux Version 4.0.1530.

Best regards

Jian Huang

Hello Jian,

Please ignore that voltage conflict warning. In the UI, you have the preferred voltage set to 1.8v while Vddshv3 is set to 3.3v and the tool gets confused and gives a warning. Logically though that's fine for the HDMI interface.

Generally, these conflict warnings are just to let the system designer know the voltage tolerances on the pins (if they differ amongst each other).

Hope it helps,

thanks,

Alex
