Part Number: DAC5662A

Hello.

below FPGA output spec.

FPGA output MIN voltage is 2V. and DAC5662A Vih spec is 2V.

Is there a problem with the communication between the two devices?

I wait for your answer. please reply about my question.

Thanks and regards.

Hi Downey,

Your FPGA's Voh is right at the edge of the minimum Vih value required for the DAC5662A. If you can make sure the VOH signals at input pin of DAC is meeting VIH requirements of the DAC you should be fine.
