Tool/software:

a) we are using for 3 LMX2592 chips in our application

1. PLL1 used for 30.72 MHz and required only sine wave, is it possible?

2. PLL2 used for 1.6GHz to 3.6GHz and required sine wave form

3. PLL3 used for 20 MHz to 8GHz required sine wave form only

above 3 conditions we required all are possible or not?

b) please provide the Gerber file for LMX2592 & Required Layer Stack up for our reference.
