S33305-50.000-X-R

Oscillators Overview

The S33305-50.000-X-R is a surface-mount crystal oscillator (XO) from Aker Technology Corp, operating at a fixed frequency of 50MHz. It utilizes HCMOS output levels and supports a supply voltage range of 1.8V to 3.3V. The device features a frequency stability of ±50 ppm and includes an enable/disable control function. Packaged in a 4-pin SMD no-lead format with dimensions of 3.2mm x 2.5mm x 1.1mm, it operates within a temperature range of -40°C to +85°C and complies with RoHS standards.

Oscillators Feature Summary

• Integrated enable/disable functionality for power management
• HCMOS output signal compatibility
• Surface-mount design for automated assembly

Oscillators Applications

• General-purpose clock generation for digital circuits
• Embedded systems requiring stable timing references
• Consumer electronics with space-constrained PCB layouts

Oscillators Procurement Notes

Verify the specific suffix 'X-R' indicates tape-and-reel packaging when ordering. Confirm that the 1.8V minimum supply voltage meets system requirements, as some variants may require higher voltages for proper operation. Ensure the 4-pin footprint matches the target PCB layout. Check for RoHS compliance documentation if environmental regulations apply to the final product assembly.

Oscillators Selection Notes

Select this component when a 50MHz HCMOS clock source is required with ±50 ppm stability. Consider the 1.8V-3.3V operating range for low-voltage applications. The compact 3.2x2.5mm package suits high-density designs. Verify that the enable pin feature aligns with system power sequencing needs compared to always-on oscillators.

Oscillators Part Context

This part belongs to the S3 series of surface-mount oscillators from Aker Technology. It shares the same physical footprint and electrical interface characteristics as other frequencies within the S33305 family, such as the 24MHz or 25MHz variants. The primary differentiator is the fixed 50MHz output frequency, while maintaining identical package dimensions and supply voltage specifications.

Oscillators Replacement Considerations

Direct substitutes include other S33305 series parts with different frequencies but identical packages, such as S33305-24.000-X-R or S33305-25.000-X-R, provided the frequency change is acceptable. Cross-brand replacements must match the 4-SMD no-lead package, 50MHz frequency, HCMOS output, and ±50 ppm stability.
