• Supports flexible input configurations including HCSL, LVDS, and LVPECL levels
• Provides programmable LVPECL output signals via I2C interface
• Designed for applications requiring precise timing and jitter attenuation

Applications

• High-speed data communication systems
• Network synchronization equipment
• Test and measurement instruments
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix '010' against official Renesas documentation to confirm factory-programmed frequencies and pinout compatibility. Confirm RoHS3 compliance status and check for End-of-Life notices or Product Change Notifications prior to procurement. Ensure the 32-VFQFN footprint matches the target PCB design requirements.

Selection Notes

Select this component when a single-frequency LVPECL clock generator with FemtoClock NG jitter attenuation is required. Consider the 300MHz maximum frequency limit and the specific input/output voltage ranges. Evaluate thermal management needs for the VFQFN package in the intended application environment.

Part Context
