What the shared parts are
- CXL controllers & memory expanders — Chips that let a server attach an extra pool of DRAM over a CXL link rather than only through the CPU's own memory channels, expanding usable capacity beyond what fits in local DIMM slots.
- PCIe/CXL switches & retimers — Fabric silicon — switches that fan a single PCIe or CXL root out to many downstream devices, and retimers that clean up the signal over longer runs — connecting accelerators, SSDs, and pooled memory back to the host.
- Controllers — The chip inside or paired with an SSD that manages NAND wear-leveling, error correction, and the drive's host interface.
- Timing & telemetry silicon — Precision timing and telemetry chips that synchronize clocks and monitor signal integrity across the network fabric.

Questions
- Do Marvell and Microchip compete?
- In this catalog they are both placed on 4 of the same parts, across 2 layers: CXL controllers & memory expanders, PCIe/CXL switches & retimers, Controllers, Timing & telemetry silicon. Sharing a part does not mean selling the same product to the same buyer, so read each row's product note.
- Which has more placements, Marvell or Microchip?
- Marvell has 13 placements and Microchip has 5. Placement counts reflect how thoroughly each company has been catalogued as well as its real breadth, so they are not a ranking.
Generated from the catalog's part-to-company table. Each placement is tagged disclosed, reported or inferred; see sources & method. Neither company is endorsed or ranked here.
