LMX2592: Difference between LMX2594

Hello team,

My customer has some experience with LMX2594, and now considering to use LMX2592.

Is it possible to use same register setting as LMX2594?
I have checked up to register 7, but I see some difference in the register maps already.

Also is there any difference in feature between LMX2594 and LMX2592?
I believe LMX2592 doesnt support SYSREF, but is there anything else?

Best Regards,
Kei Kuwahara
