AD7984 maximum propagation delay in chain

Category: Hardware
Product Number: AD7984

Hello,

how do I calculate the maximum allowable propagation delay of the CLOCK between device A and device B in "CHAIN MODE WITHOUT BUSY INDICATOR" in the AD7984 Datasheet page 22?

https://www.analog.com/media/en/technical-documentation/data-sheets/AD7984.pdf

Is this t_HSDO - t_HSDISCK  = 3ns - 3ns = 0n --> so no margin there?

Thank you

Best regards,

rostilj

    Hi  ,

    Upon checking its timing diagram, there would not be a delay in propagating from the SDO of device A going to the SDI of device B. I think what we need to focus on more is the timing delay…
