PCIe Gen5/Gen6 & CXL Retimer / Switch IC — connectivity IC

PCIe Gen5/Gen6 & CXL Retimer / Switch IC — connectivity IC

Companies committing: astera-labs, enfabrica.

Opportunity: Hyperscale AI racks need PCIe Gen5→Gen6 + CXL retimers/switches just to keep host-to-accelerator links alive at scale; this is Astera Labs' core ALAB-listed business.

Astera Labs is the public-market poster child for AI rack connectivity — the role density across PCIe/CXL retimer chips, validation, formal, and switch architecture shows the product line is in fast iteration, not just one product. Enfabrica jumps in from the NIC side. Missing piece: independent second source.
