S22505T-27.000-X-R

Oscillators Overview

The S22505T-27.000-X-R is a 27 MHz HCMOS crystal oscillator manufactured by Aker Technology Corp. It operates on a 2.5V supply and features an enable/disable control function. The component utilizes a 4-SMD, No Lead package with ultra-mini dimensions of 2.5mm x 2.0mm. It offers a frequency stability of ±50ppm and a load capacitance of 15pF. The device supports a duty cycle of 55% and is designed for surface mount applications.

Oscillators Feature Summary

• Integrated enable/disable functionality for power management
• Ultra-miniature surface-mount package design
• HCMOS output signal compatibility

Oscillators Applications

• General purpose clock generation in embedded systems
• Digital signal processing timing references
• Microcontroller system clocks

Oscillators Procurement Notes

Verify the specific suffix 'X-R' indicates tape and reel packaging configuration. Confirm that the 2.5V operating voltage aligns with target circuit requirements. Ensure the enable pin logic levels are compatible with host controller outputs to prevent unintended oscillation states during system initialization or sleep modes.

Oscillators Selection Notes

Select this model when space constraints require a 2.5x2.0mm footprint. Choose based on the need for active low/high enable control rather than continuous operation. Verify that the ±50ppm stability meets system timing tolerance requirements compared to higher precision alternatives.

Oscillators Part Context

This part belongs to the S22505T series of ultra-miniature crystal oscillators from Aker Technology. The series typically includes various frequencies and voltage options within the same physical package form factor. It represents a standard XO variant distinct from temperature-compensated (TCXO) or voltage-controlled (VCXO) types.

Oscillators Replacement Considerations

Direct substitutes include other S22505T series variants with identical pinout and envelope but different frequencies such as S22505T-25.000-X-R or S22505T-24.000-X-R. Cross-brand replacements must match the 4-SMD no-lead package and HCMOS electrical characteristics.
