PEX8603-AB50NI G

Analog Switches - Special Purpose Overview

The PEX8603-AB50NI G is a PCI Express Gen 2 switch integrated circuit manufactured by Broadcom Limited. It provides three lanes and three ports for high-speed data interconnection. The device operates within a temperature range of -40°C to +85°C and utilizes a QFN-136 surface-mount package. This component supports PCIe Gen 2 specifications with a data rate of 5.0 GT/s, enabling non-blocking switching capabilities for system expansion.

Analog Switches - Special Purpose Feature Summary

• Supports PCI Express Gen 2 interface standards
• Provides three-lane, three-port switching architecture
• Designed for industrial operating temperature ranges

Analog Switches - Special Purpose Applications

• PCIe endpoint expansion in industrial systems
• Server storage connectivity solutions
• Embedded computing platform interconnects

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'NI' against official Broadcom documentation to confirm package type and material composition. Confirm end-of-life status and availability through authorized channels, as distribution may be restricted or limited depending on regional regulations and stock levels.

Analog Switches - Special Purpose Selection Notes

Select this component when a compact three-port PCIe Gen 2 switch is required for space-constrained designs. Ensure the QFN-136 package fits the PCB layout constraints. Compare with the TQFP-128 variant if through-hole mounting or different pinout requirements are necessary for the specific application design.

Analog Switches - Special Purpose Part Context

This part belongs to the Broadcom PEX860x series of PCIe switches. It serves as a connectivity solution for expanding PCIe buses in server and storage environments. The device integrates multiple lanes into a single port configuration to facilitate efficient data routing between host processors and peripheral devices.

Analog Switches - Special Purpose Replacement Considerations

The PEX8603-AB50TQI G offers identical electrical functionality but uses a TQFP-128 package instead of QFN-136. Verify pin compatibility and thermal performance before substituting, as the physical footprint differs significantly between the two package types.
