In order to meet the needs of PCS sublayer frame synchronization at 10 Gbps transmission rate

depth studying of 10 G Ethernet PCS sublayer frame synchronization principle and common frame synchronization detection method

considering the chip area and detection efficiency

a parallel frame synchronization detection module is designed

which solves the problems of the synchronous header cross data blocks and the alignment of bits in the frame synchronization detection

improves the frame synchronization efficiency

and can meet the requirements of the 10 Gbps frame synchronization of the PCS sublayer. ModelSim is used to verify the design of the frame synchronization detection module

the results show that the module can effectively achieve the 10 Gbps PCS sublayer frame synchronization detection function

the frame synchronization speed is markedly improved

with strong adaptability

robustness and stability.
