Procurement Notes

Verify component status as listings indicate potential end-of-life or discontinuation notifications. Confirm specific ordering suffixes against official Renesas documentation to ensure correct factory pre-programmed configurations. Check for recent Product Change Notifications regarding assembly sites or labeling updates before procurement.

Selection Notes

Select this model when LVPECL outputs are required alongside flexible HCSL/LVDS/LVPECL input compatibility. Ensure the 32-VFQFN footprint fits the PCB layout constraints. Verify that the 300MHz maximum frequency meets system requirements. Compare against other FemtoClock NG variants if multiple independent PLLs or different output types like LVDS are needed.
