Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix against official documentation to confirm automotive qualification status. Ensure the ordering part number matches the required package variant and environmental rating. Cross-reference the manufacturer datasheet revision to validate pinout compatibility and electrical specifications before finalizing procurement orders.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when extending PCI Express traces beyond standard length limitations without requiring retiming. Compare channel count and power consumption against lower-density alternatives like the DS80PCI402 if fewer lanes are sufficient. Confirm that the target application requires passive equalization rather than active clock recovery provided by retimers.
