With compatibility for PIPE 4.4 interface protocol, this Peripheral Component Interconnect Express (PCIe) x4 PHY complies with PCIe 4.0 Base Specification. Support for extra PLL control, reference clock control, and inbuilt power gating control results in lower power usage. Additionally, because the previously described low power mode option is programmable, the PHY is extensively useful for a variety of applications with diverse power consumption considerations.
