Abstract

The present application relates to systems, chips, and electronic devices for cross-chip clock synchronization are provided. The clock synchronization system comprises a first clock adjustment link, a second clock adjustment link and a clock phase difference detection module; The first clock adjustment link is configured to adjust a phase delay of the input clock signal and generate a first clock signal based on the adjusted input clock signal; A first clock adjustment link spanning two chips, the first clock adjustment link includes a first cross-chip transmission circuit; the second clock adjustment link is configured to adjust a phase delay of the input clock signal and generate a second clock signal based on the adjusted input clock signal; the second clock adjustment link includes a delay replication circuit, transmission delay of the first cross-chip transmission circuit being consistent with the transmission delay of the delay replication circuit; the clock phase difference detection module is configured to detect a phase difference between the first clock signal and the second clock signal. The present application can reduce clock skew between cross-chips.
