PORESET_B voltage value

[paulagarcía-mor]

Hi,

I would like to control the signal PORESET_B of the T2080 with a FPGA. The supply voltage of the FPGA pin is 1V5 and the supply value for PORESET_B is 1V8.

On the datasheet I just found that the recommended value for OVDD(PORESET_B supply) is 1V8 +- 90mV, but I would like to know it a value of 1V5 would be recognised or do I need to adapt the voltages.

Thank you.

Please check the FPGA Data Sheet whether it could provide not less than 1.25V high level of the signal - if "yes" direct connection is possible.
