Rambus is to acquire PLDA, a leader in Compute Express Link (CXL) and PCI Express (PCIe) digital solutions, and AnalogX, a provider of low power multi-standard connectivity SerDes IP solutions.

Both acquisitions are intended to address what the company has called a ‘generational shift’ in the data centre space and the development of next generation systems and new architectures.

CXL and PCIe will be critical enablers for these new systems, delivering the high-speed interconnects between processors, accelerators, memory and network devices needed to tackle demanding workloads in AI/ML and HPC applications.

PLDA’s CXL 2.0, PCIe 5.0 and PCIe 6.0 controller and switch IP will expand the Rambus portfolio and accelerate the time to market for complete CXL interface subsystems.

The acquisition of AnalogX augments the Rambus family of PCIe 5.0 and 32G Multi-protocol PHYs with SerDes technology specifically built for ultra-low power and very low latency, expanding the addressable applications and available process nodes

Together with PLDA, AnalogX’s expertise in DSP-based design and PAM4 signalling will accelerate the Rambus roadmap for PCIe 6.0 and CXL 3.0 solutions and provide critical building blocks for the CXL Memory Interconnect Initiative.

“As data centres move to a disaggregated model, high-speed connectivity will be instrumental to unleashing the performance of data-intensive computing platforms,” said Luc Seraphin, president and CEO of Rambus.

Both transactions are expected to close in the third quarter of 2021.
