PCIe

PCI Express (peripheral component interconnect express), officially abbreviated as PCIe or PCI-e, is a high speed computer expansion bus standard. It is a common motherboard interface for graphics cards, hard disk, SSD and Internet hardware connections.
The PCIe 5.0 supports data rate up to 32 GT/s and channel loss budget for system board is -16dB@16 GHz based on PCI-SIG documents. Extremely low capacitance TVS under 0.2 pF is recommended to promise the signal integrity in PCIe Gen. 5.0.
