Procurement Notes

This part number is officially classified as obsolete by the manufacturer. Verification of current availability should focus on surplus distributors or secondary market sources rather than direct manufacturing channels. Confirm RoHS3 compliance and check for any Product Change Notices (PCN) related to assembly site changes or labeling updates before procurement.

Selection Notes

When selecting this component, verify that the required output count matches the 1:8 ratio capability. Ensure the system design supports LVPECL or LVDS logic levels. The 48-VFQFN package requires appropriate PCB layout considerations for thermal dissipation via the exposed pad. Cross-reference with the official datasheet for specific pin configurations and electrical characteristics.

Part Context

The 8T49N008A-066NLGI belongs to the IDT8T49N008I family of programmable clock generators. It is designed for applications demanding low phase jitter and flexible frequency synthesis. The '066' suffix typically denotes a specific frequency configuration or packaging variant within the broader product line.

Replacement Considerations

Direct replacement options are limited due to the obsolete status. Potential substitutes include other models from the FemtoClock NG series such as the 8T49N004A or 8T49N008A variants, provided they meet the specific frequency and output requirements. Verify pin compatibility and electrical specifications before substitution.
