PLL or PLC clock module for USRP1

GNU Radio
1

Hi all,

I wonder if you know of a clock module for USRP1 with phased locked
loop or phase locked crystal (preferred)
which has a 10MHz reference clock input and provide ~64MHz clock that
will be used on USRP1

Thanks in advance.

You’re unlikely to find that as an off-the-shelf item.

I remember that I saw something taking power from the USRP1 fan power
input
having external clock input and providing a 52MHz or close clock to be
used but I could not find that link again when I looked for it
So I thought maybe someone used it in here so I can get information
about it.
Did anyone designed or used a similar module/board.
Thanks

There was/is a 52MHz high-quality clock board for the USRP1, intended
for OpenBTS applications.
My understanding is that the board (through Olifantasia??) is no
longer available.

I have already seen that and it is not exactly what I wanted/meant but
thank you.
I hope someone else has done/used something similar and help me.
Thanks in advance.
