    PCIe is the most common protocol in high speed serial standards to connect components in embedded systems. It leverages SerDes (Serializer/De-serializer) technology to deliver throughput and latency performance greater than what is possible with wide parallel bus technology.
    Terminus Circuits offers best-in-class PHY IP for PCIe 4.0/3.0/2.0. The PHY is designed for low latency, low power, small form factor, high interface speeds for high performance computing. The PHYs comes complete with a physical media attachment (PMA) hard macro that supports PCIe 4.0, 3.0, and 2.0 protocols and a physical coding sublayer (PCS) and soft macro for PCIe that is PIPE4.3 compliant.

    MIPI M-PHY HS Gear 4 IP is compliant with the MIPI serial communication protocol for use in mobile systems where performance, power, and efficiency are key criteria. It is the foundation for several upper layer protocols which manage complex data transfer functions. Each of these protocols is optimized for its particular purpose, such as data storage, data transfer, display, camera, memory sharing, and radio interface. Scalability and modularity are also important features of the MIPI M-PHY, as these features allow designers to more easily adapt to evolving system and application requirements.
