PCIe 4.0 Serdes PHY IP in 7nm

Description and Features

The high-bandwidth applications benefit from the low power, multi-lane, and high-performance PCIe 4.0 PHY IP's 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 data rates of 2.5Gbps, 5.0Gbps, and 8.0Gbps for PCIe 3.1, PCIe 2.1, and PCIe 1.1, respectively. The PCIe 4.0 IP may satisfy the needs for various channel circumstances since it supports both TX and RX equalisation methods.
