IDT part on Carrier Card

kgervel

Hi, I've seen in a couple of other forum posts about the discrepancy between the UltraZed BOM/schematics, which list the IDT clock synthesizer p/n as 5P49V5935B521LTGI, whereas the actual part installed is 5P49V5935B536LTGI.  

My question is, what is the difference between these two part numbers?  The datasheet that I find for them is a generic datasheet from IDT for the 5P49V5935 family, but there are no specific details on distinguishing between the longer part numbers.  Can someone clear this up for me?  I am designing a custom carrier card and want to make sure I understand this part selection.

    Hi there,

    The 5P family is the Versaclock.
    This means it is a programmable part and the last digits on there helps you to know what the programming is, within the part.

    If your custom carrier needs to perform some of the same functions, I would suggest that you copy the part that produces the clocks that you need.  If you need some other set of clocks, you will need to acquire the clock that fits those needs.  If you need to go that route, please contact your local FAE for assistance.

    As for the two part numbers that you listed, there was a small update to the boards, where we ended up placing the 536 part instead.

    Thank you for pointing out that the BOM was not updated on our website, I will get that taken care of as soon as I can.

    The Version of IO CC that you have is likely revision 1.1.04+, which uses the 536 as described above.
