[time-nuts] Will a TADD-2 work with 50 MHz input?

[Jim Lux]

I have a 50 MHz oscillator I want to measure, and I have a TICC and a 10 MHz source (to run the TICC) and a good 1pps.  I assume that if I divide the 50 down to 5 (e.g. with the TADD-2) I can do the measurement.  The question is whether the TADD (or some other inexpensive off the shelf thing) can handle that high an input frequency.
Or, is that pushing the PIC beyond its limits?

Same sort of question for 100 MHz.
