XpressPCS for PCIe 5.0 is a logic design IP core implementing the Physical Coding Sublayer part of the PCIe 5.0 Specification. XpressPCS exposes a PIPE compliant user interface allowing connection to any PIPE 5.2 and PIPE 4.4.1 compliant PCIe PHY/MAC. It also exposes a transmit and receive interface to the PHY/PMA electrical sub-block along with messaging interface for Equalization and Lane Margining functionality. The comprehensive PHY/PMA interface is the result of years working with PCIe SerDes developers and guarantees XpressPCS IP can be used with any SerDes PMA implementation. XpressPCS is the ideal solution for PHY IP vendors and technology companies developing their own SerDes PHY looking to complement their SerDes PMA implementations with a full-featured silicon proven PIPE-compliant interface.
