I just use a 1:1 PLL.  Some will argue that phase locking two 
oscillators running at the same frequency is not optimal, but I have 
found that it can work very well.  YMMV.  Perhaps locking a 100 MHz 
OCXO to the PRS10 and dividing its output down to 10 MHz could yield 
better results (and perhaps not) -- but I have no desire to start 
collecting 100 MHz OCXOs and culling them to find the best one, so 
that hypothesis is left for someone else to investigate.

Best regards,
