Macom supports PCIe, CXL connectivity with high performance chipset

MACOM (MTSI) Technology announced the availability of a new chipset to overcome the distance limitations of traditional PCI Express and Compute Express Link connectivity by enabling high speed, low latency communication over optical fiber. Designed to maintain signal integrity and reduce latency, the chipset consists of the MATA-38794 transimpedance amplifier and the MALD-38795 VCSEL driver. By consolidating sideband signaling into a single fiber pair, MACOM’s solution reduces the cost and complexity of optical transceivers and cabling. As data centers and high-performance computing environments demand increasing bandwidth and reach, MACOM’s chipset enables PCIe extension up to 100 meters over multimode fiber. The chipset supports eight PCIe 6.0 lanes at 64 Gbps PAM4, while also transporting critical sideband signals including clock, reset, wake and communication channels like USB and Ethernet over an additional fiber. This ensures full PCIe bus transparency across extended distances.
