Hello Emanuel,

The oscillator is the 520M05DA40M0000, the datasheet is located at
http://www.ctscorp.com/components/Datasheets/008-0371-0.pdf

A temperature range test of the B200mini has not been done so there is no
certified temperature range. The oscillator is specified for -30C to +85C.

The FPGA utilization for a very recent master code is as below.

Regards,
Derek

Hello \
Derek, \
 Thanks \
for your answers. Indeed, \
I overlooked that the third SMA connector is for the 1PPS or 10MHz \
reference. Which \
VCTCXO exactly are you using? The schematic does not state any specific part \
number. \
 The \
B200mini data sheet states a version called B205mini-i with a larger FPGA. Is this \
version available soon and will RFNOC be possible with this version or \
not? \
 Regards,
 Emanuel

Hello Emanuel,
</div>
The B200mini has an SMA connector \
which accepts either a 1PPS or 10MHz reference so no breakout adapter is needed. The \
built in VCTCXO has a basic accuracy of 0.5ppm. The datasheet I have is generic for a \
range of oscillator frequencies and doesn&#39;t have a phase noise plot for the \
40MHz version. I am looking to see if we have that information available. The \
clocking structure of the B200mini can be seen on page 4 of the schematics. <a \
href="http://files.ettus.com/schematics/b200mini/b200mini.pdf" \
target="_blank">http://files.ettus.com/schematics/b200mini/b200mini.pdf</a>
 </div>
The FPGA used, the Spartan-6 \
XC6SLX75, is the same as the B200 has so unfortunately it is not possible to use \
RFNoC with the B200mini. The FPGA resource usage is also about the same as the B200, \
though I&#39;ll check with one of the designers for actual \
numbers. </div>

Dear Ettus team,
 
Your new B200mini looks great, very nice work indeed. I have \
some general questions you could probably answer easily, as I did not find additional \
information on that on your website: 1. Do you ship the B200mini with a sort of \
breakout adapter such that the B200mini can easily be fed from an external 10MHz \
source? 2. You \
also have a B200mini-i series with an industrial temperature range: what is the \
allowed temperature range for the normal B200mini? Does the B200mini-i series also \
cover an extended temperature range for the oscillator?
3. Do you have some \
specifications of the used oscillator? Accuracy/drift? A link to the datasheet is \
fine for me. 4. \
How many FPGA resources are still available on the FPGA? \
5. Is it possible to use RFNOC \
with the B200mini series? 
Best regards,
Emanuel
