About the Broadcom PEX 89144 PCIe 5.0 Switch
Fast replacement paths are critical for accessories in production environments — and the Broadcom PEX89144 PCIe 5.0 Switch delivers the enterprise-grade reliability and performance that mission-critical systems demand. This large-scale switching silicon from Broadcom represents the latest generation of PCIe fabric architecture, engineered for data-intensive workloads that cannot tolerate bottlenecks. The PEX89144 operates as a PCIe 5.0 compliant switch with 144 total PCIe lanes running at 32 GT/s per lane, delivering aggregate bidirectional bandwidth of up to 1.84 TB/s. Full backward compatibility with PCIe 4.0, 3.0, and 2.0 ensures seamless integration into existing infrastructure, while support for flexible lane bifurcation — including x1, x2, x4, x8, and x16 port widths — enables dynamic reconfiguration to match workload requirements. The silicon supports both transparent and non-transparent bridging modes, offering system designers maximum flexibility in fabric topology.
Storage architects, AI infrastructure teams, and enterprise IT procurement specialists implementing next-generation data center expansions rely on switching silicon like the PEX89144 to unlock full bandwidth potential across NVMe, GPU, and accelerator interconnects. Integrated error detection and correction — including PCIe 5.0 compliant advanced error reporting, explicit congestion notification, and link CRC — protects data integrity at scale. Hardware-based receiver lane margining per the PCIe 5.0 Base Specification provides proactive signal quality monitoring, while dual management interfaces (PCIe configuration space and SMBus/I2C sideband) enable both in-band and out-of-band monitoring. CXL compatible ecosystem alignment positions this switch for emerging compute disaggregation architectures.
The Broadcom PEX89144 is available in commercial and industrial grade options tailored to your thermal and operational requirements.
