Procurement Notes

Verify the specific suffix 'GGG' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides valid traceability documentation for this telecommunications-grade component. Cross-reference the package marking with the official 64-CABGA outline drawing to prevent counterfeit substitution during assembly.

Selection Notes

Select this component when designing SONET/SDH equipment requiring low jitter synchronization for OC-48 or OC-192 signals. Confirm that the system power supply maintains the required 2.97V to 3.63V range. Verify that the host board supports the 64-CABGA surface mount footprint and that the thermal design accommodates the specified -40°C to 85°C operating environment.
