Abstract

The embodiment of the invention relates to the technical field of communication equipment, and discloses a circuit board, which comprises a first signal line and a second signal line which are arranged adjacently, and further comprises a grounding plane and a conductive layer connected with the grounding plane, and the conductive layer is arranged between the first signal line and the second signal line. The embodiment of the invention also provides communication equipment. According to the circuit board and the communication equipment provided by the invention, the crosstalk problem of a communication line can be effectively reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication equipment, and in particular to a circuit board and a communication equipment having the circuit board. Background technique [0002] With the advent of the information age, the transmission speed of signals continues to increase, and the rate of high-speed SerDes (SERializer / DESerializer) has increased from 25Gbps to 56Gbps, and is moving towards 112Gbps. With such a high rate, routing high-speed signals throughout the system presents many, many design challenges. In the past, design considerations were typically done only at the component level, but next-generation multi-Gbps designs require a holistic analysis of the signal channel path. R&D personnel cannot only focus on one component, but must analyze and optimize the interaction of all components in the entire channel. During the analysis and optimization process, the crosstalk problem of communication lines ...
