Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'SQE' against the manufacturer's current datasheet to confirm pinout compatibility and functional equivalence with other variants in the DS80PCI402 family. Ensure that the automotive grade designation aligns with your system's environmental requirements. Cross-reference the package outline drawing to validate footprint dimensions before finalizing procurement orders.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when extending PCIe traces beyond standard copper length limits in automotive or industrial environments. Compare channel count requirements against similar devices like the DS80PCI800 if eight lanes are needed instead of four. Evaluate power consumption constraints relative to the device's operating current at target data rates. Confirm thermal management strategies for the WQFN-48 package under maximum load conditions.
