Abstract

A printed circuit board with a high-speed differential signal wiring structure comprises a high-speed differential signal control chip, a first to eighth coupling capacitor welding pad, a first to fourth connector welding pad, a plurality of transmission lines and a first to fourth shared welding pad, wherein the high-speed differential signal control chip is selectively connected with the first to fourth connector welding pad through the first to fourth shared welding pad. The printed circuit board with the high-speed differential signal wiring structure can be selectively connected with a plurality of connectors.

Description

technical field [0001] The invention relates to a printed circuit board with a high-speed differential signal wiring structure. Background technique [0002] Existing general personal computer mainboard, except central processing unit, chipset, also has several connectors that are used to install adapter card. With the development of the electronic industry, the function of the chip is further improved. The same chip can support different connectors. For example, a peripheral component interconnection (PCI) chip can support the connector of the first specification, such as SAS (Serial Attached SCSI). The hard disk of the transmission specification can also support the connector of the second specification at the same time, for example, a hard disk supporting the SATA (SerialATA) transmission specification. Different motherboard products will choose to install different connectors. For example, some manufacturers require only connectors of the first specification to be insta...
