Connecting device of clock lines on a server motherboard, server motherboard, and server

Abstract

The invention discloses a connecting device of clock lines on a server motherboard, a server motherboard, and a server. The connecting device comprises: N connectors arranged between a clock source onthe server motherboard and a controller for connecting clock cables, wherein the N connectors include a first connector connected to a clock source and a second connector connected to a controller. It can be seen that the invention provides a plurality of connectors for connecting clock cables on a server motherboard, and the length of the clock cables connected between the two connectors can bechanged to meet the equal-length design requirements of the clock lines without winding the cables on a board card, so the trace layout of other links is not affected. Moreover, when the peripheral configuration changes, only the length of the clock cable connected between the two connectors can be changed without redesigning of the board, so the design cost is reduced.

Description

technical field [0001] The invention relates to the field of server link design, in particular to a connection device for a clock line on a server main board, a server main board and a server. Background technique [0002] At present, a controller, a clock source, and slots for connecting peripheral terminal devices are arranged on the main board of the server. When designing a server motherboard, the equal-length design of the clock line is particularly important, that is, the length of the clock line between the clock source and the controller should be equal to the length of the clock line between the clock source and the terminal equipment. However, once the clock line on the board is designed according to the current peripheral configuration, the length of the clock line on the board cannot be adjusted, so that the clock line on the board is only applicable to the current peripheral configuration. If the peripheral configuration changes, the board needs to be redevelop...

AI Technical Summary

Problems solved by technology

However, when the clock line that needs to be wound on the board is long, it will occupy a large space on the board, thereby affecting the wiring layout of other links; moreover, when the peripheral configuration changes, the original winding The clock line cannot meet the new configuration requirements. At this time, the board needs to be redesigned, which increases the design cost
