T2M PCI Express PCIe 4.0 Serdes PHY IP in 16FFC

PCIe 4.0 Serdes PHY IP in 16FFC

Description and Features

For high-bandwidth applications, the PCIe 4.0 PHY IP delivers high-performance, multi-lane capabilities and a low-power design. A full variety of PCIe 4.0 Base applications are supported by the PCIe 4.0 IP, which also complies with the PIPE 4.4.1 specification. The IP integrates high-speed mixed signal circuits to support PCIe 4.0 traffic at 16Gbps. It is backward compatible with PCIe 3.1 data rate at 8.0Gbps, PCIe 2.1 data rate at 5.0Gbps and PCIe 1.1 data rate at 2.5Gbps. The PCIe 4.0 IP may satisfy the needs for various channel circumstances since it supports both TX and RX equalisation methods.
