Hi,

By connecting Vref of TFP410PAP to 0.9V will I be able to properly function the IC at 1.8V? I do not have any 3.3V ports left. As it is mentioned as Adjustable CMOS I hope this will be possible.

Regards,

Jeevan

The Vref is the input reference voltage, it selects the swing range of the digital data inputs (DATA[23:0], DE, HSYNC, VSYNC, and IDCK±).

But TFP410 has to be operate (DVDD, PVDD, TVDD) between min of 3V and max of 3.6V.

Thanks

Hi,

Thanks, so from your input I can conclude that the digital data inputs can be fixed to 1V using the Vref and the IC will do its intended function given that DVDD,PVDD and TVDD are fixed to 3.3V(3.3V in my case).

Thanks,

Jeevan
