I can't see what the other ICs on Bert's board are, but I gather it is 
using the timing module's sawtooth error data to set the programmable 
delay line. This seems to be a good option if the receiver of the PPS 
signal cannot accept adjustment data, but what can it do if the qErr 
data indicates the next pulse is going to be late instead of early?
