LMX2595EVM: LMX2595EVM interfacing with external controller
Part Number: LMX2694EPEVM
at the moment im ussing the pll of the microcotroller to generate the 100MHz
i know that is not a realiable reference, but it keeps things working
Could you please , also suggest a pad (close to Y1) to pull the 3,3 V
Any 7mmx5mm XO can fit the board. You can pick either a single-ended output or differential output XO. Table 4 of the EVM user's guide has the instruction how to populate the EVM to match the XO.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Noel Fung:
From Table 4: the pads for R24 and C34 dot not exist at all
i guess there are some disvadvantages when populating a XO on the LMX2694EPEVM (thats why, TI did not release the product with XO on ). Therefore, I think , that not any 7mmx5mm fullfil this job..
Thanks for you reply
In reply to giovanny Mateus:
R24 and C34 are at the bottom side of the board.
The lead time of a high performance XO is very long and the supply is sometime not stable, this is the reason why we are not putting a XO on the board.
ok, i found them!
thanks for your support
most of the commercial/affordable crystalls (50MHz) had 4 pads, not exactly 6 as in the Eval board.
to be sure, before ordering a Crystal, i would like to have a layout (altium,...) of the board , in oder to review the pad dimension for soldering
is it posible?
you can use the LMX2594EVM design file, it has the same footprint XO..
