• Applications supporting Nontransparent Bridging functions

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct distribution channels. Confirm moisture sensitivity level (MSL 4) and lead-free status (No) prior to integration into production workflows.

Selection Notes

Select this part for designs requiring 32 lanes and 24 ports of PCIe Gen2 connectivity. Ensure compatibility with the 324-FCBGA footprint and verify power rail configurations for 1V, 2.5V, and 3.3V supplies. Consider the industrial temperature grade (-40°C to +85°C) if operating in demanding environments.
