[time-nuts] time-nuts] FTS 1050A

[ed breya]

You're right, Max, I didn't think about subsampling for this - that 
would give a more efficient implementation - no LPF, say two 74HC390s 
to divide by 10,000, a 74HC74 with one half as a divide by two to get 
to 20,000, the other half as the sampler/downconverter, and a 
74HC4046A PLL. So, four common ICs to do the DSP/PLL portion.

Here's an example sampler application I just looked up, showing 
appropriate connections:
