Today I assembled the new FA-SY 2 from Funkamateur. The clock worked
without any problem with the USRP. I calibrated the clock with Kal and
got a max frequency offset of +-60Hz which is very close to the required
0,05 ppm/ 0,1ppm for a BTS. I configured the clock to 52 MHz output.
I think the FA-SY 2 is with an output level of 0,7V is more suitable
than the FA-SY 1 with CMOS output level.
Like Andy Fung mentioned some time ago the input level for the AD9513
should not be more than 2 V. So the FA-SY 2 is more suitable for the
USRP. Maybe someone can updated this info in the wiki.
