PipeCORE PCI-Express and CXL PHY

1-64Gbps PCI-Express Gen6 and CXL PHY

The Alphawave PipeCORE PHY IP is a high-performance, low-power, PCIe Gen1 – Gen6 PHY, that is capable of also operating at 64Gbps PAM4 PCIe Gen6 rates. It includes a hardened PMA layer and a soft PCS layer deliverable. The PipeCORE is based on the industry leading AlphaCORE DSP architecture.

The PipeCORE is power and performance optimized for the strenuous challenges of PCIe and is targeted to deliver unparalleled bandwidth for the next generation of computing interfaces.

Targeted for 45+dB of channel loss for for PCIe Gen 1 – Gen6 and CXL NRZ and PAM4 rates, the PipeCORE delivers a power-optimized, physical layer IP that yields more than 400Gbps of data throughput per millimeter of Silicon perimeter.
