An accurate way to calibrate a frequency source is to use a high-resolution counter/timer to measure the beat frequency, or phase difference, between the source to be calibrated and a reference such ...

Recently, for some reason, I have been seeing a lot of references to the good old MM5314/5/6 clock ICs from National Semiconductor. These were some of the first 40-pin LSI (large-scale integration) ...
