Abstract
An adjustable high resolution timer () for synchronizing a local clock to an external reference clock includes frequency offset acquisition and compensation unit () configured to acquire a frequency offset difference between the local and external reference clock and to generate frequency adjustment signals based on the frequency offset difference; a time drift tracking and adjustment unit () configured to continuously monitor the local and external reference clocks for phase offset differences therebetween and to generate timing adjustment signals based on the phase offset difference; a nanosecond timer core unit () configured to generate a frequency and phase adjusted nanosecond timer output signal in response to the frequency adjustment signals and timing adjustment signals; and a pulse generation unit () for generating a plurality of output pulse signals that are synchronized with the external reference clock in response to the frequency and phase adjusted nanosecond timer output signal.
