clock loss detection

Hi all! Any ideas to build a fast and robust clock loss detector? A reference clock is available.

A related concept is estimating the clock frequency of your 'other' clock relative to your reference. For example, lets say you have a 50MHz on-board clock. Think about how you would use that to estimate the frequency of the other clock source.

As Kosh suggests, have a crack at it, and come back with code and questions.

Cheers,
