The PCIe PHY designed by Terminus Circuits is crafted to support high-performance computing with low latency and power consumption. It facilitates seamless connectivity in embedded systems by adopting the most prevalent serial protocol for high-speed interconnects. With configurations supporting PCIe generations 4.0, 3.0, and 2.0, it features a complete physical media attachment (PMA) hard macro and a physical coding sublayer (PCS) that adheres to PIPE4.3 standards. Designed for flexibility, this PHY ensures minimal delay and efficient operation even under demanding conditions.
Central to the design is its capability to support multiple lane configurations allowing for data transfer rates of up to 16Gbps per lane. The PHY is distinguished by its robust calibration mechanisms for termination resistors, maintaining precise impedance control, and its three-tap transmitter equalizer that adjusts emphasis levels dynamically. Enhanced features such as the continuous time linear equalizer (CTLE) and decision feedback equalizer (DFE) are integrated to maximize data integrity across channels.
This PCIe PHY is a versatile component, fit for a wide array of applications ranging from data centres to consumer electronics. Its strategic support for bifurcation and quadfurcation modes adds to its adaptability, allowing multiple lanes to work independently or in concert. With a design that includes comprehensive electrostatic discharge (ESD) protection and operation over extensive temperature ranges, it underscores reliability and robustness for a multitude of deployment environments.
