We are currently using Si5348 as a network synchronizer in our network edge systems. we also want to use Si5389B as an additional network synchronizer to support more peripherals. We are unable to find IBIS models for Si5389 from the above link "https://www.silabs.com/support/resources.ct-software.p-timing?query=IBIS". I request you to provide us the IBIS simulation model for Si5389B to move forward with our design.
On a side note, since Si5348B and Si5389B belong to the same family of network synchronizers and have the same input and output frequencies, by any chance do they have the same input and output buffers so that we can use the si5348 IBIS model for Si5389 as well.
Thanks and Regards,
Actually, the Si5389 is an MCM where one of the die is the Si5348. The other is an MCU. So as long as you're only interested in clock input/output performance, you can use the Si5348 IBIS model. Since the package is slightly different, there could be some minor differences based on package parasitics, but the drivers/receivers are the same.
