DAC80504: DAC80504 Digital Isolator

USER170220
Prodigy 40 points
Part Number: DAC80504

Hi there,

I would like to isolate the circuit between CPLD and DAC. However this is the first time to work on isolator.

The datasheet shows SCKL frequency  is 50MHz for write operation and the minimum time of SPI is  5 ns, which belongs SDI setup.

Does 150Mbps digital isolator adequate?

    Hi Onurcan,

    Welcome to E2E and thank you for your query. I think the isolator team will be in the best position to answer this. I am reassigning the organization.

    Hi Onurcan,

    Are you investigating our ISO764xFM?

    Unfortunately this isolator does not support 50MHz SPI speeds due to propagation delay specs, and we do not have digital isolators which meet this requirement at the moment. I hope this is not an unpleasant experience for your first time using digital isolators; please let me know if there is more information I can assist with.


    Thank you,
