Procurement Notes

Verify the package type against the datasheet. The model suffix 'S' indicates a 16-TSSOP package, while the official datasheet specifies the AB-557-03 series as a 14-pin QFN component. Confirm that the local source description matches the required physical footprint before procurement.

Selection Notes

Select this component for designs requiring low jitter and high reliability in compact spaces. Ensure the system voltage falls within the 2.25V to 3.6V range. Verify thermal requirements against the -40°C to +85°C operating specification. Check if HCSL or LVCMOS output levels match the downstream receiver inputs.

Part Context

This part belongs to the AB-557-03 series, which are ultra-miniature SMD clock generators. The series is characterized by its solid-state storage and lack of external crystals. It is designed to replace traditional quartz oscillators in space-constrained applications.

Replacement Considerations

Check pinout compatibility if substituting other clock generators. The datasheet notes that for frequencies other than 100MHz, users should consider the ASEMDxx series.
