S33305-25.000-X-R

Oscillators Overview

The S33305-25.000-X-R is a surface-mount crystal oscillator from the S3 series, manufactured by Aker Technology Corp. It provides a standard frequency output of 25 MHz with a frequency stability of ±50 ppm. The device utilizes HCMOS output levels and operates on a single 3.3V supply voltage, drawing a maximum current of 12mA. It features an enable/disable function for power management. The component is housed in a compact 4-SMD, no-lead package measuring 2.5mm in width, 3.2mm in length, and 1.1mm in height. It supports an operating temperature range from -40°C to +85°C and complies with RoHS standards.

Oscillators Feature Summary

• Integrated enable and disable functionality for active power control
• HCMOS logic output levels compatible with standard digital interfaces
• Compact surface-mount design suitable for space-constrained PCB layouts

Oscillators Applications

• General-purpose clock generation for microprocessors and microcontrollers
• Timing reference for data communication interfaces
• Synchronization sources in consumer electronic devices

Oscillators Procurement Notes

Verify that the specific suffix '-R' corresponds to tape and reel packaging requirements if automated assembly is planned. Confirm the exact load capacitance specification, as distributor listings may vary between 12pF and 15pF for this series. Ensure the 3.3V supply rail meets the maximum current draw of 12mA during operation. Cross-reference the RoHS compliance status with the latest manufacturer documentation to ensure regulatory adherence for the target market.

Oscillators Selection Notes

Select this model when a 25 MHz timing source with ±50 ppm stability is required for 3.3V logic systems. The HCMOS output is appropriate for direct interfacing with standard digital inputs without additional level shifting. Consider the enable pin requirement if dynamic power saving is necessary. The 4-pin SMD footprint requires adequate clearance for reflow soldering processes. Evaluate thermal performance within the specified -40°C to +85°C operational range for the intended environment.

Oscillators Part Context

This component belongs to the S3 series of surface-mount oscillators from Aker Technology Corp. The series offers various frequencies with consistent physical dimensions and electrical characteristics. The S33305-25.000-X-R specifically targets applications needing a reliable 25 MHz clock signal. It shares the same package and basic electrical profile as other variants in the series, differing primarily in output frequency and specific suffix designations for packaging or tolerance.

Oscillators Replacement Considerations

Direct substitutes include the S33305-32.000-X-R and S33305-50.000-X-R from the same manufacturer, provided the application can accommodate different frequencies. Other 25 MHz HCMOS oscillators in the 3225 package with similar stability and voltage specifications may serve as alternatives, though pinout and enable functionality must be verified.
