Abstract
A count value generator includes an input for receiving a synchronizing count value, a counter configured to increment at a local frequency, the local frequency being faster than the synchronizing frequency, and an interpolator for determining a frequency ratio between the local frequency and the synchronizing frequency and for determining an increment value for the counter dependent on a relative amount of a maximum value of the counter with respect to the frequency ratio is disclosed. The counter generates a count value including a predetermined number of bits representing integer values and output as the lower order bits of the output count value and additional lower order bits that represent fractional portions of the integer values. The counter includes output circuitry for outputting the synchronizing count value and the predetermined number of bits representing integer values generated by the counter as the lower order bits of the count value.
