Procurement Notes

Verify the specific suffix 'NLGI' against the manufacturer's current datasheet to confirm package type and temperature range specifications. Ensure compatibility with system voltage levels and input signal standards before integration. Confirm availability status as product lifecycles may change. Cross-reference ordering information with official Renesas documentation to avoid discrepancies in part identification.

Selection Notes

Select this component when flexible frequency translation is required for networking or communications designs. It is suitable for applications needing support for various differential input standards and programmable output frequencies. Consider its low phase jitter characteristics and I2C configurability for system integration requirements.

Part Context
