There is a phase-noise chart on the product datasheet:

Will the N310 schematics be posted? I’m specifically needing to find out the
phase noise of the TCXO and GPSDO.
Thanks,

Just chiming in to say you aren't crazy -- I've seen similar results in my
RFNoC loopback testing. There's a critical spp that you can't go below at
full rate without experiencing over/underflows. I didn't take the time to
dig down to the bottom of it, so I can't be of too much help here except to
Hello Ben:
USRP N210 samples at 100MS/s (with an additional 4x interpolation in case of Tx
- making it 400MS/s). The maximum effective sampling rate, however, is
bottlenecked by the connection between the USRP and the PC. The 1Gbps Ethernet
connection can keep up with a 25MS/s 16bit I-Q data s
I tried using the packet_resizer block which improved things a little
bit but not significantly. I figured that as soon as the difference
between the spp (coming from the Radio) and the set packet size in the
resizer block is too large, I get overruns again. I increased the
STR_SINK_FIFOSIZE of
