| 摘要 |
Devices and methods for varying individual periods or cycle times of upconverted clock signals within a corresponding reference clock cycle are disclosed. In some embodiments, these varying cycle times may improve signal synchronization between the upconverted clock and the reference clock. In different embodiments, different types of counters and counting circuits keep track of the number of elapsed upconverted clock cycles in order to determine the specific upconverted clock cycles with longer cycle times. In some embodiments, a signal may be sent to a delay line to change the amount of delay between upconverted clock pulses, thereby increasing or decreasing a specific upconverted clock cycle time or period. In some embodiments the specific upconverted clock cycle(s) changed in each reference clock cycle may vary, which may further improve reconciliation between the upconverted clock cycles and the corresponding reference clock cycle.
