LMKDB1108: Finding a clock generator like LMKDB1102

Part Number: LMKDB1108
Other Parts Discussed in Thread: LMKDB1102, CDCE6214-Q1, , LMK3H0102

Hi Sirs

I am finding a clock generator which's behavior like LMK1102 for PCIE application。

Our processor have one pair differential clock output, and plan to feed to two differential pcie clock input, so it seems I can use LMKDB1102.

However, from datasheet, LMKDB1102 seems unavailable, so could you check any alternate part has similar function as I described? ( up to PCIE Generation 4.0  )

By the way, I am not sure CDCE6214-Q1 can be the candidate or not, could you help to check?

Thank you

    Hello Luis,

    The LMKDB1102 will be released to market early July. That's when the data sheet will be available. However, we have samples available for the LMKDB1102 and we could ship some out to you. If interested, please fill out the table below:

    SOP

    Volume in k/y

    Status/Action

    anchor socket 1

    Osc/Clock Gen/Buffer/DPLL

    CTS WIN$ Amt/ system

     

     

     

     

     

     

     

     

     

     

     

     

     

    If you want a buffer, a device that takes in a frequency and buffers out multiple copies of that same frequency, them the LMKDB1108 is already released to market and can be ordered. Also, to clarify, are you feeding one input into the buffer and outputting 2 copies of that input?

    Best,

    Andrea

    Hi Andrea

    We only want two output for PCIE client, so using LMKDB1108 would be waste, and size is bigger

    For one input into buffer and output 2 copies, yes. 

    CDCE6214-Q1 can do this?

    Hello Louis,

    Yes it can. The LMK3H0102 can also do it and it could be a better option to your system.

    Best,

    Andrea
