Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm package integrity and date codes upon receipt. Ensure compatibility with existing system voltage levels and thermal requirements before integration. Check for alternative sourcing options due to discontinuation status.

Clock Buffers, Drivers Selection Notes

Select this component when a single differential clock source must drive multiple downstream loads with LVDS or LVPECL interfaces. Consider the 650 ps propagation delay and 1.5 GHz frequency limits against system timing constraints. Evaluate the VFQFPN-32 footprint availability during PCB layout design.

Clock Buffers, Drivers Part Context

This device belongs to the IDT8T79S838 series of fanout buffers. It serves as a replacement for legacy IDT components, maintaining functional equivalence while adhering to Renesas manufacturing standards. The specific NLGI suffix denotes the package type and temperature grade configuration.

Clock Buffers, Drivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-compatible replacements should be verified against official Renesas cross-reference lists.
