Analog Switches - Special Purpose Procurement Notes
This component has reached the End-of-Life (EOL) status as indicated by official discontinuation notifications dated June 23, 2025. Verification of authenticity is critical due to limited availability in the secondary market. Buyers should confirm the specific revision and physical condition of units obtained from third-party distributors, as standard supply channels no longer support new orders.
Analog Switches - Special Purpose Selection Notes
Designers should consider the transition to newer generations such as the PEX8748, which offers PCIe Gen 3 capabilities. The PEX8648-BB50RBI G remains suitable for legacy systems or cost-sensitive designs where Gen 2 performance is sufficient. Engineers must account for the discontinued lifecycle status when planning long-term production runs or maintenance cycles for existing infrastructure.
Analog Switches - Special Purpose Part Context
The PEX8648 belongs to the Broadcom ExpressLane family of PCIe switches. This series is engineered to provide scalable, high-bandwidth, non-blocking interconnections for servers and storage systems. The device integrates advanced packet switching technology to minimize latency while maximizing throughput for demanding enterprise applications.
Analog Switches - Special Purpose Replacement Considerations
The PEX8748 is a direct architectural successor offering PCIe Gen 3 speeds. Other compatible options include the PEX8632 for reduced lane counts or the PEX8664 for higher port density configurations.
