The PCIe subsystem incorporates a 1-lane PCIe compliant PHY (PIPE) interface to connect to a SERDES-based PHY. The PCIe PHY module consist of a SERDES module and a PCIe PCS (Physical Coding Sub-block) module. The SERDES module converts parallel data into PCIe serial signals and the PCIе PCS module provides an industry standard PIPE Interface to PCIe MAC. The frequency of the PIPE interface can be 62.5MHz or 125MHz depending on whether the system is operating in Gen1 or Gen2 mode. The width of the PIPE interface remains constant at 32-bits for all modes of operation. For more information on the SERDES module, see Section 12.2.3, Serializer/Deserializer (SerDes).
