PEX8619-BA50BC G

Specialized Overview

The Broadcom PEX8619-BA50BC G is a PCI Express Gen2 switch integrated circuit featuring 16 lanes and 16 ports. It operates within a supply voltage range of 0.95V to 1.05V and supports an ambient operating temperature from 0°C to +70°C. The device utilizes a 324-ball HSBGA package with dimensions of 19x19 mm, designed for surface mount installation. This component integrates DMA capabilities and functions as a high-performance interface IC for scalable interconnection architectures.

Specialized Feature Summary

• Supports PCIe Gen2 data rates with integrated 5.0 GT/s SerDes technology
• Enables multi-host architecture configurations including host failover modes
• Provides non-blocking internal switch architecture for full line rate performance
• Integrates Direct Memory Access (DMA) functionality

Specialized Applications

• Server systems requiring scalable high bandwidth interconnects
• Switch fabrics and aggregation networks
• Peer-to-peer multi-host architecture implementations
• Clustered system designs utilizing host failover capabilities

Specialized Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate differences in packaging or qualification. Confirm RoHS compliance status through current manufacturer declarations. Check for active Product Change Notices regarding design or marking updates. Ensure compatibility with existing board layouts given the 324-HSBGA footprint requirements.

Specialized Selection Notes

Select this component when a 16-port PCIe Gen2 solution with DMA support is required. Consider the thermal characteristics associated with the 324-ball HSBGA package during PCB layout. Evaluate the need for multi-host failover features versus standard single-host operation. Verify that the 0.95V to 1.05V power rail specifications align with the target system design constraints.

Specialized Part Context

This part belongs to the Broadcom ExpressLane family of PCIe switches. It serves as a successor or variant within the PEX86xx series, designed for enterprise infrastructure connectivity.
