Thanks John,

I wonder if you have decided whether to use your existing clocks and
add a clock doubler to output to the Touch or to use double frequency
clocks? I am tempted to use a clock doubler, which would be jittery,
but since I am reclocking the final output to the DAC anyway with the
receiver-frequency clocks, it shouldn't matter in the end. All the
clock doubler circuits I know require a perfect square wave (50% duty
cycle) input. My Tent clocks are not specified for duty cycle, but they
look good on the scope. I wonder how sensitive you think the Touch
processor is to clock jitter, and whether a doubler circuit would be
good enough? Thanks for your help.

Jack
