  • Multi-chip system, chip, and clock synchronization method
    Patent number: 11385675
    Abstract: A multi-chip system includes a first chip and a second chip. The first chip is configured to generate a first symbol clock signal according to a first clock signal from a first oscillator. The second chip is configured to generate a second symbol clock signal according a second clock signal from a second oscillator, detect a difference between the second symbol clock signal and the first symbol clock signal to generate an error signal, and synchronize the first symbol clock signal and the second symbol clock signal according to the error signal.
