All SerDes interfaces are configured as point-to-point connections. It is assumed that the connection is made between the SoC and another device that is compliant to the appropriate industry standard. The list of supported standards is given below.
This chapter deals with the physical layer and, therefore, it is the electrical specifications in these standards that are relevant. For more information regarding protocol compliance (1), see the device-specific Datasheet.
Standard | Bit Rate (Gbps) | Reference Clock Frequency (MHz) | Bus Width (bits) |
---|---|---|---|
PCI Express 4.0 Gen1 | 2.5 | 19.2, 20, 24, 25, 26, 27, 100 | 8 |
PCI Express 4.0 Gen2 | 5.0 | 19.2, 20, 24, 25, 26, 27, 100 | 16 |
USB 3.1 Gen1 SuperSpeed | 5.0 | 19.2, 20, 24, 25, 26, 27, 100 | 16 |
