Procurement Notes

Verify the specific ordering suffix 'AUG' against official Renesas documentation to confirm package type, temperature grade, and lead-free status. Ensure compatibility with required ITU-T and Telcordia standards for your specific network topology. Cross-reference part numbers carefully as suffixes often dictate mechanical and environmental specifications distinct from the base model number.

Selection Notes

Select this component when designing systems requiring dual-channel SyncE PLL functionality compliant with G.8262 and G.813 standards. Consider the 196-CABGA package size and 3.3V operation constraints. Evaluate the 18-35Hz loop bandwidth range against your jitter filtering requirements. Confirm that the -40°C to 85°C industrial temperature range meets your deployment environment needs.

Part Context

This device belongs to Renesas' family of synchronous Ethernet PLL solutions designed for high-performance networking applications. It addresses the need for precise clock recovery and generation in telecommunications equipment. The two-channel architecture allows for independent or coupled operation depending on system design requirements, supporting complex synchronization topologies.

Replacement Considerations

Consult official Renesas cross-reference guides for verified substitute part numbers. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure any replacement maintains compliance with the same ITU-T and Telcordia standards required by the original design specification.
