Abstract
Circuits and methods are provided for clock adjustment. A method for clock adjustment includes receiving feedback clocks from independent ASIC modules. The method includes comparing the feedback clocks to a reference clock to generate phase measurement values. A common delay is removed from the phase measurement values to form normalized correction values. Target phase values and clock select values are selected using the normalized correction values. And, clock signals to independent ASIC modules are adjusted based on the target phase values and clock select values.
