The one used on USRPs shipping now is 20 ppm with this part number --
EC2620ETTS-64.000M
From Ecliptek. They are pin compatible.

By the way, could someone tell me what is the part number of the
VCTCXO shipped with USRP Rev 4.5? In the bill of materials of the
trunk I see "CTX286LVCT-ND", which seems to correspond to
CB3LV-3C-64M0000 in the manufacturer's nomenclature.
The datasheet
(http://www.ctscorp.com/components/Datasheets/008-0256-0_E.pdf)
specifies +/- 50 ppm, but I have read somewhere that actually it is
+/- 20 ppm.
Which is the right one?
Thanks,
Carles.
