Oscillators Procurement Notes

Verify the exact frequency specification against the official datasheet, as generic part numbers may indicate programmable ranges rather than fixed frequencies. Confirm that the required PG-series programming instrument is available for field configuration. Ensure the ceramic SMD package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a customizable frequency solution is required without maintaining extensive inventory of pre-programmed units. The field-programmable nature allows for flexibility in production lines. Consider the availability of the PG-3200 or compatible programmer for on-site configuration needs.

Oscillators Part Context

This model belongs to the CPPFX series of field-programmable crystal oscillators from Cardinal Components. These devices are designed to offer the benefits of custom oscillators with the logistical advantages of standard blank components. The series supports various output types and voltage levels, catering to diverse electronic design requirements.

Oscillators Replacement Considerations

Direct replacements require matching the field-programmable capability and ceramic SMD package. Verify compatibility with existing programming infrastructure. Generic fixed-frequency oscillators cannot substitute this part without redesigning the system to accommodate the specific 77.76 MHz requirement.
