- Industrial control systems operating in extended temperature ranges
Procurement Notes
This product is listed as discontinued or end-of-life. Verify current availability status through authorized distributors. Check for Product Change Notifications (PCN) regarding manufacturing site changes or packaging updates. Ensure compliance with RoHS3 specifications if required for your application. Confirm lead times and final purchase decisions carefully due to potential obsolescence.
Selection Notes
Select this component when eight synchronized LVPECL clocks are needed from a single source. Ensure the input signal matches supported formats like LVDS or HCSL. Verify that the system power supply stays within the 2.375V to 3.465V range. Consider the 32-VFQFN package size for PCB layout constraints. Compare against other FemtoClock NG variants if different output counts or frequencies are required.
Part Context
Part of the FemtoClock NG family, designed for low-jitter clock generation. The 8T49N008A variant specifically provides eight outputs. The suffix NLGI indicates specific packaging and environmental ratings. This series is commonly used in high-performance digital systems where timing accuracy is critical.
Replacement Considerations
Check for direct pin-compatible substitutes within the 8T49N008A series. Review Renesas documentation for updated models replacing discontinued parts. Verify electrical compatibility before substitution. Contact manufacturer support for recommended alternatives.
