Systems and methods for a PLL-adjusted reference clock

摘要

A system is provided, the system includes a phase-locked loop (PLL) that multiplies a reference clock input to generate a communication link clock signal. The system also includes a transmitter/receiver (TX/RX) module coupled to the PLL, the TX/RX module is configured to transmit and receive data based on the communication link clock signal. The system also includes a divider coupled to the PLL, the divider receives the communication link clock signal and outputs a PLL-adjusted reference clock that approximates the reference clock input. The PLL-adjusted reference clock is used to generate at least one other communication link clock signal.
