Specialized Procurement Notes

This component is classified as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors. Verify RoHS compliance status carefully, as some variants in this series are non-compliant. Confirm the specific suffix ZABCG against official datasheets to ensure correct package and environmental ratings before procurement.

Specialized Selection Notes

Select this part for applications requiring a 10-lane PCIe Gen2 switch topology. Ensure the design supports the 900 mV to 1.1 V core voltage requirements. The 324-CABGA package necessitates appropriate PCB layout considerations for thermal management and signal integrity. Compare against newer generations if long-term supply stability is a critical project constraint.
