Does anyone have any information about possible drop-in alternates for the SI5346B-D-GMR part from Skyworks? I cannot find this part in-stock anywhere and need it ASAP for a project I am working on. My setup uses an external crystal resonator as the reference clock and uses two differential inputs and outputs.

For stocking options the SI5394P-A-GM looks to be the most similar.
