Procurement Notes

Verify the specific suffix '070' against official Renesas documentation to confirm pinout and electrical characteristics, as suffixes often denote specific packaging or configuration variants. Confirm current availability status, as this part number may be subject to discontinuation notices. Ensure compliance with RoHS3 standards and check moisture sensitivity level (MSL) ratings for proper handling during assembly.

Selection Notes

Select this component when LVPECL outputs are required alongside flexible input compatibility including HCSL, LVDS, or LVPECL. The 300MHz maximum frequency and 1:4 fan-out capability suit applications needing moderate speed distribution. Verify that the 32-VFQFN package fits the PCB layout constraints and thermal requirements of the design.

Part Context

This device belongs to the FemtoClock NG series, which focuses on low-jitter clock generation. The 8T49N004A base model typically offers programmable features for various clocking needs. The specific variant 8T49N004A-070NLGI represents a fixed-frequency or pre-configured version within this family, distinguished by its output format and package type.

Replacement Considerations

Check for direct replacements within the 8T49N004A family with compatible suffixes. Consider the 8T49N004A-058NLGI8 for similar LVPECL output and VFQFN packaging, verifying if the frequency and input specifications match the application requirements.
