S22505T-27.000-R

Oscillators Overview

The S22505T-27.000-R is a standard crystal oscillator (XO) manufactured by Aker Technology Corp, operating at a fixed frequency of 27 MHz. It utilizes HCMOS output logic levels and supports a supply voltage range from 1.8V to 3.3V, with typical operation at 2.5V. The device features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, specifically designed for surface-mount applications. The unit offers a frequency stability of ±50 ppm and includes a load capacitance specification of 15pF. It operates within a temperature range of -40°C to +85°C and complies with RoHS standards.

Oscillators Feature Summary

• Includes hardware enable and disable pin functionality for power optimization
• Designed in a small form factor ultra mini-CSMD package for space-constrained layouts

Oscillators Applications

• General purpose clock source for embedded systems
• Timing reference for consumer electronics devices
• Clock generation for industrial control modules

Oscillators Procurement Notes

Verify the specific suffix codes on the ordering information to ensure correct packaging and tolerance specifications. Confirm that the required supply voltage aligns with the 1.8V to 3.3V operational range. Check for any specific automotive or high-reliability variants if the application demands stricter environmental qualifications beyond the standard commercial grade. Ensure PCB footprint matches the 4-SMD no-lead dimensions provided in the mechanical drawings.

Oscillators Selection Notes

Select this component when a stable 27 MHz reference is required for HCMOS-compatible logic families. Consider the enable/disable feature if system power efficiency is a priority. Evaluate the ±50 ppm stability against the timing requirements of the target application. Compare the physical dimensions of the 4-SMD package against available board real estate constraints relative to other oscillator series offerings.

Oscillators Part Context

This part belongs to the S22505T series of surface-mount crystal oscillators from Aker Technology. The series provides various frequency options within a standardized small outline package. These components are positioned as general-purpose timing solutions for commercial electronics, offering a balance between performance, size, and cost-effectiveness compared to larger through-hole alternatives.

Oscillators Replacement Considerations

Direct substitutes include the S22505T-27.000-X-R variant, which shares identical electrical characteristics but may differ in packaging tape-and-reel specifications. Other frequencies within the same S22505T series can be considered if the system design allows for frequency adjustment.
