1. A method of calibrating a first clock signal using a second clock signal, the method comprising:

  • generating incremented counter values at a counter responsive to edges of the second clock signal;

    for at least two different edges of the first clock signal, performing calculations based on respective incremented counter values; and

    determining a relationship between the first and second clock signals using linear regression using the calculations based on the respective incremented counter values for the at least two different edges of the first clock signal.
