| Description | 48-Lane, 12-Port PCI Express Gen 3 (8.0 GT/s) Switch IC with Multi-Host and Non-Transparent Bridge (NTB) capability. |
Product Overview
The PEX8748-BA80BCG is a high-performance 48-lane, 12-port PCI Express Gen 3 ExpressLane™ switch IC developed by Broadcom (formerly PLX Technology). Optimized for high-density multi-host systems, high-end storage arrays and GPU clusters, this device delivers ultra-low latency and a maximum data rate of 8.0 GT/s per lane. Equipped with built-in Non-Transparent Bridging (NTB) and multi-host functions, it enables stable communication between multiple root complexes without performance bottlenecks. Featuring comprehensive on-chip diagnostic tools and advanced low-power design, PEX8748-BA80BCG is an ideal core component for cloud data centers, high-performance computing (HPC) and AI server systems.
Core Advantages
Ultra-High Performance & Bandwidth
Featuring 48 PCIe lanes compliant with Gen 3 standard and 8.0 GT/s per lane transfer speed, this switch provides powerful parallel throughput. It perfectly supports connection for multiple high-speed NVMe storage devices and high-performance accelerator clusters to eliminate transmission bottlenecks.
Flexible Multi-Host and NTB Subsystems
Integrated hardware-based Non-Transparent Bridging (NTB) supports dual-host failover, distributed computing and multi-host cluster deployment, effectively improving system redundancy and overall computing scheduling capability.
Advanced ExpressLane™ Diagnostics
Built-in real-time performance monitoring, signal integrity testing, loopback and error detection functions simplify hardware debugging and system verification, greatly reducing testing and maintenance costs.
Highly Efficient Thermal and Power Design
Dynamic power management automatically disables idle ports and lanes to reduce power consumption and heat generation. It runs stably in densely deployed server racks and meets long-term continuous operation requirements.
