T2M PCI Express PCIe 4.0 SerDes PHY IP

PCIe 4.0 SerDes PHY IP

Description and Features

This Peripheral Component Interconnect Express (PCIe) x4 PHY is compliant with PCIe 4.0 Base Specification with support of PIPE 4.4 interface spec. Lower power consumption is achieved due to support of additional PLL control, reference clock control, and embedded power gating control. Also, since a fore mentioned low power mode setting is configurable, the PHY is widely applicable for various scenarios under different consideration of power consumption.

T2M provides a portfolio of silicon-proven IP for PCI Express consisting of controllers, PHYs, verification IP, IP Prototyping Kits, Software Development Kits and Interface IP Subsystems. As the industry standard for PCI Express, solution which T2M offers is in volume production and has been successfully implemented in a wide range of applications.
