Clock Buffers, Drivers Procurement Notes

Verify the specific suffix '8' against the official datasheet to confirm packaging details. Mouser listings indicate limited availability or special order status for this part number. Confirm moisture sensitivity level and reflow soldering profiles prior to procurement to ensure compliance with handling requirements.

Clock Buffers, Drivers Selection Notes

Select this component when a 2-to-8 fanout ratio with differential outputs is required. Ensure the system power supply voltages match the supported levels for the chosen output format (LVPECL, LVDS, or HCSL). Verify that the input clock source compatibility aligns with the specified differential input types.

Clock Buffers, Drivers Part Context

This part belongs to the Renesas 8P39 series of clock buffers. The 'NLGI' designation typically indicates a lead-free, RoHS-compliant variant in a QFN package. The '8' suffix often denotes a tape-and-reel packaging option, distinct from tray packaging found in other variants like the 8P391208NLGI.

Clock Buffers, Drivers Replacement Considerations

Direct substitutes within the same family include the 8P391208NLGI. Verify pinout compatibility and electrical parameters before substitution. Other Renesas clock buffers with similar 2:8 ratios may require schematic adjustments.
