A physical layer (PHY) IP solution for consumer electronics, the PCIe Gen 2 PHY IP allows for customization. The PHY IP complies with the PCIe2.0 fundamental specifications while integrating mixed signal circuits to provide 2.5GT/s and 5.0GT/s data transfer speeds. Physical Media Attachment (PMA) and Physical Coding Sublayer (PCS) are the two levels that make up the PCIe2.0 PHY IP. It simply connects to either the PCIe2.0 MAC layer utilizing the industrystandard PIPE-3.0 interface.
The PCIe2.0 PHY IP transceiver is optimized for low power consumption and small die area while retaining great result and data throughput. The PCIe2.0 PHY IP includes an on-chip physical transceiver solution with ESD protection, a built-in self-test module with inbuilt jitter injection, and a dynamic normalization circuit that ensures full support for high-performance configurations.
