Pin Definition

Pin Definition

The Atlas 300 complies with the standard PCIe card protocol (PCI Express® Card Electromechanical Specification Revision 3.0) and provides a PCIe x16 port. It provides the following data signals: A group of PCIe 3.0 x16, with the maximum rate of 8 Gbps/lane, is used for transmitting service data. A group of SMBus signal, with the maximum rate of 100 Kbps, is used for the out-of-band management unit to monitor the Atlas 300. For details about the Atlas 300 signals, see Table 5-1 to Table 5-5.
