CDCI6214: Can I use an XTAL with CL=18pf with the CDCI6214??

Hi,

I'm not familiar with XTAL osc circuits.

Using the TICS Pro software, I don't seem to be able to use a Crystal with Load Capacitance requirement of 18pf.

I set Cstray to 4.5pf, CL ext to 0pf and CL to 18pf. Software errors.

Questions:

1/. What do I need to do to make an ABM3C-25.000MHZ-D4Y-T work with the CDCI6214?

2/. Should I use a different 25M XTAL with 50ppm? If so, can you recommend one and tell me what numbers to program into the CDCI6214.

Thanks
