You can feed the OctoClock from the X310, and then use the OctoClock's output to drive the N210. All devices will be synchronized, in frequency, and the N210s will be synchronized in time, but the X310 and N210s will not be synchronized in time. However, that timing offset you might able to calibrate out, I wouldn't expect it to drift.
