TFP410: TFP410 Design Support

Shyam

What is the VOH and VOL of the SoC? TFP410 supports adjustable 1.1V to 1.8V and standard 3.3V CMOS input signal Levels. 

Please see below for the VREF voltage recommended operating condition

And input VIH and VIL requirement

Thanks

Hi David,

Thanks for the quick response.

So I can connect the RGB888 data signals from my SoC which are working at 1.2V directly to the TFP410 without any issue and it will work if the below VIH and VIL conditions are met. Please correct my I f am wrong.

VIH and VIL conditions to meet:

Also please let me know, other than this Vref, do I need to check anything further when working in low swing mode ie 1.2V mode.

Shyam

Hi David,

Thank you for the clarification.

What is the Vref voltage need to set for low swing mode operating at 1.2V?

Also I will update here with the SoC VOH and VOL details soon.

Vref for low-swing mode will be between the min of 0.55V to max of 0.95V. But you have to set the Vref voltage to satisfy the SoC VOH and VOL requirement.

Thanks

David
