Hi Team, 

May I ask for help? Our customer have a concern as shown below:

"I saw on the lmk05028 evb that they use tcxo pn:7n-10.000mbp-t
Im searching for smaller component 
I want to use pn:sit5155aicfk33e0-10.0000x 
Is it posible to use it?"

I was able to get the datasheet of 7n-10.000mbp-t online and the datasheet of was provided by the customer.
Kindly see attached:

    Hello Gerald,

    There shouldn't be a problem using the SiT5155AI-FK-33E0-10.0000x instead.

    Please note that the SiT5155AI has a slightly worse frequency stability (0.5 ppm) than the 7n (0.28 ppm), so there might be a slight degradation in phase noise performance at the output. Also please note that the terminations will differ for the SiT5155AI from that of the 7n.

    Regards,

    Kia Rahbar
