Core offering

XConn Technologies designs and sells PCIe Gen 5 and CXL 2.0/3.1 switching silicon (ASICs) for AI and HPC data center interconnects. Its products enable high-radix memory pooling, disaggregation, and low-latency connectivity between CPUs, GPUs, and memory devices, and are sold as switch chips and reference designs to datacenter OEM vendors and hyperscalers.

Product overview

XConn Technologies is a semiconductor company specializing in high-performance interconnect switches for AI data centers and HPC applications. Founded in 2020, the company offers a portfolio of CXL (Compute Express Link) and PCIe (Peripheral Component Interconnect Express) switch silicon products. The core product line includes the XC50256 CXL 2.0/PCIe Gen 5.0 hybrid switch chip (marketed as Apollo), the XC51256 PCIe Gen 5.0 switch chip, and the Apollo 2 second-generation hybrid switch supporting CXL 3.1 and PCIe Gen 6.2 standards. XConn was acquired by Marvell Technology in February 2026 for approximately $540 million, with XConn's switching silicon technology now integrated into Marvell's product portfolio under the Structera brand (Structera S 30260 CXL switch and Structera S 60260 PCIe 6.0 switch). The products are sold as ASICs to datacenter OEM vendors and hyperscalers, and XConn maintains active contributions to industry standards including UALink, CXL Consortium, PCI-SIG, and Open Compute Project.

Scale indicators3 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Marvell Technology: Marvell is XConn's acquirer and a broad incumbent in data center connectivity silicon (Ethernet, DSP, PCIe retimers, switches), competing in many of the same sockets and now incorporating XConn's switching technology under the Structera brand.
• Broadcom: Broadcom is the dominant incumbent in switching silicon (Ethernet switches, PCIe switches) and serves the same hyperscaler and OEM customer base; it competes broadly in the data center interconnect category where XConn operates.
• Renesas Electronics: Renesas (through IDT) sells PCIe switches and is a broad semiconductor incumbent supplying interconnect products to server and datacenter customers, competing with XConn's switch silicon.
• Microchip Technology: Microchip (including the former Microsemi and IDT PCIe switching portfolios) offers PCIe switches and is a broader incumbent semiconductor vendor serving datacenter OEMs and hyperscalers in adjacent interconnect categories.

Emerging players

• ScaleFlux: ScaleFlux is an emerging player in CXL Type 3 memory controllers (MC500) that partnered with XConn on CXL 3.1 interoperability, addressing the same CXL memory pool use cases from the device side.
• Credo Technology: Credo is an emerging AI interconnect silicon vendor focused on high-speed retimers/AECs and PCIe/CXL connectivity; it is a co-demonstration partner with XConn and addresses the same hyperscaler AI cluster connectivity opportunity.
• Mobiveil: Mobiveil provides CXL and PCIe IP/controller silicon, competing with XConn's switching ASICs at the controller/IP layer and serving similar hyperscaler and OEM customers seeking CXL-capable silicon.

Direct peers

• Astera Labs: Astera Labs is a direct competitor in AI data center connectivity silicon, offering PCIe/CXL retimers, smart cable modules, and CXL controllers aimed at the same hyperscaler and OEM buyers as XConn's switch ASICs.

Others

• MemVerge: MemVerge is a memory software (Big Memory) partner that jointly demonstrates CXL memory pooling solutions with XConn; it is an adjacent ecosystem participant enabling the same AI memory-pooling use case rather than a direct silicon competitor.
• Synopsys: Synopsys is an EDA and design IP provider whose PCIe/CXL IP was used by XConn to build its switches; it is an ecosystem enabler (and collaborator) rather than a direct switch competitor.
