PipeCORE PCI-Express and CXL PHY

1 to 64Gbps PCI-Express (PCIe) Gen6 and CXL PHY

The Alphawave PipeCORE PHY IP is a high-performance, low-power, PCIe Gen1 to Gen6 PHY, that is capable of also operating at 64 Gbps 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.


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 PCIe Gen1 to Gen6 and CXL NRZ and PAM4 rates, PipeCORE delivers a power-optimized, physical layer IP that yields more than 400 Gbps of data throughput per millimeter of silicon perimeter.

High Speed Performance

Low power, DSP based architecture provides robust operation over long copper backplanes.

Low Power Architecture

Low power DSP architectures enable next generation PCIe Gen6 and CXL interfaces. Supports L1 substate power management. Option power gating implemented.

Robust Training

Integrated microcontroller per lane enables fast PCIe training in both foreground and background adaptation to enable both NRZ and PAM4 rates.

Industry Standard Support

The PipeCORE PCIe Gen1 to Gen6 PCS layer supports both PCIe 5.0 and PCIe 6.0 and has been validated with leading PCIe and CXL Controllers. Supports low latency architecture optimal for CXL applications.

Receive Equalization

Designed for closed eye, backplane systems up to 45dB of insertion loss at Nyquist with NEXT for NRZ and 38dB for PAM4 PCIe Gen6. Digital CDR meets strict PCIe Jitter Tolerance IO Density.

Power Optimization

Built for high performance, PipeCORE is capable of delivering equalization for up to 45 dB channels, while minimizing power consumption for NRZ and PAM4 rates.


Supports 1, 4, 8, and 16 lane configurations, different IP options available for north/south versus east-west orientations. PipeCORE also supports multiple rows of stacking for high density switching applications, and can also support multiple different metal options for SOC flexibility.
