Hi Ranjini,

We are happy to help. Are you just asking to look over the analog input interface? Or is there something else more specific that you might want us to check over?

Thanks,

Rob

Hi Rob,

Please check the input section and ADC circuitry.

Hi Rob,

Can i connect the ADC output pins to 2.5V or 3.3V bank of FPGA?

I'm having only HP bank of FPGA (1.8V). Can i connect both the controls and ADC outputs to this bank?

Hi Ranjini,

the input section and ADC circuitry looks fine.

Regards,

Rob

Hi Ranjini,

Because this is an LVDS interface this should be fine. Need to check the datasheet for the VOH and VOL levels on the digital outputs in order to make the proper interface. See page 14 of the datasheet.

Regards,

Rob
