Oscillators Procurement Notes

Verify the specific suffix 'R' against the manufacturer's current datasheet to confirm packaging and tape-and-reel specifications. Ensure the required 3.3V supply voltage aligns with the target system's power rails. Confirm that the HCMOS output levels are compatible with the receiving logic inputs. Check for any recent revisions to the enable/disable pin configuration or electrical characteristics prior to finalizing procurement orders.

Oscillators Selection Notes

Select this component when a stable 32.768 kHz reference is needed for timekeeping applications. The ±50 ppm stability is adequate for most general-purpose real-time clock implementations. Consider the 3.3V supply requirement and ensure the system architecture supports this voltage level. The enable/disable feature makes it suitable for battery-powered designs where power conservation is critical during inactive periods.

Oscillators Part Context

This oscillator belongs to the S33305T series from Aker Technology Corp, which offers various frequency options within a standardized small outline package. The series is designed for consumer electronics and industrial applications requiring reliable timing sources. Similar models in the family include different frequencies such as 24 MHz or 20 MHz, but share the same physical footprint and electrical interface standards.

Oscillators Replacement Considerations

Direct substitutes may include other 32.768 kHz HCMOS oscillators in 4-SMD packages with identical pinouts. Verify that replacement parts support the same 3.3V supply and enable/disable functionality. Cross-reference mechanical dimensions to ensure compatibility with existing PCB footprints. Confirm that the replacement component meets the required ±50 ppm stability specification.
