Core Insights - MACOM Technology Solutions Inc. has launched a new chipset designed to enhance PCI Express (PCIe) and Compute Express Link (CXL) connectivity over optical fiber, addressing distance limitations and enabling high-speed, low-latency communication [1][2]. Product Overview - The new chipset includes the MATA-38794 transimpedance amplifier (TIA) and the MALD-38795 VCSEL driver, which together maintain signal integrity and reduce latency by consolidating sideband signaling into a single fiber pair [1][2]. - The chipset supports PCIe extension up to 100 meters over multimode fiber, facilitating eight PCIe 6.0 lanes at 64 Gbps PAM4, while also transporting essential sideband signals such as clock, reset, wake, and communication channels like USB and Ethernet [2]. Industry Context - PCIe is crucial for disaggregated computing, providing high bandwidth connections between components like GPUs and CPUs, and enabling a more efficient computing model by using photonic interconnects [3]. - The extension of PCIe over fiber is deemed essential for the next generation of disaggregated computing infrastructure, as stated by MACOM's CEO, Stephen G. Daly [4]. Company Information - MACOM designs and manufactures high-performance semiconductor products for various industries, including Telecommunications, Industrial and Defense, and Data Centers, serving over 6,000 customers annually [5]. - The company has achieved multiple certifications, including IATF16949, AS9100D, ISO9001, and ISO14001, and operates facilities across the United States, Europe, and Asia, with headquarters in Lowell, Massachusetts [5].
