S22505T-32.768K-R

Oscillators Overview

The S22505T-32.768K-R is a standard crystal oscillator (XO) manufactured by Aker Technology Corp, operating at a nominal frequency of 32.768 kHz. It utilizes HCMOS output logic and functions within a 2.5V supply voltage range. The device features an enable/disable control pin for power management optimization. It is housed in a compact 4-SMD, No Lead package with dimensions of 3.2x2.5 mm, designated as 4-VDFN. The maximum supply current is specified at 2.5 mA, ensuring low power consumption suitable for battery-operated applications.

Oscillators Feature Summary

• HCMOS output interface for digital signal compatibility
• Integrated enable/disable functionality for power control
• Compact surface-mount package design

Oscillators Applications

• Real-time clock circuits in portable electronics
• Microcontroller system timing references
• Low-power embedded monitoring systems

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tolerance specifications. Confirm that the 4-VDFN footprint matches the target PCB layout. Cross-reference the enable/disable pin configuration with the schematic requirements. Ensure compliance with RoHS directives if required by the end product regulations.

Oscillators Selection Notes

Select this component when a precise 32.768 kHz reference is required for timekeeping or low-frequency synchronization. The HCMOS output level is suitable for direct interfacing with standard digital logic families. The enable feature allows for dynamic power management in battery-constrained designs. Consider the small form factor for space-limited mobile devices.

Oscillators Part Context

This oscillator belongs to Aker Technology's standard XO series designed for general-purpose timing applications. The 32.768 kHz frequency is a industry standard derived from binary division of higher frequencies, commonly used in RTCs. The 4-pin SMD variant offers a balance between size and thermal performance compared to larger packages.

Oscillators Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, HCMOS output type, 2.5V operation, and 4-VDFN (3.2x2.5mm) footprint. Verify pinout compatibility, specifically the enable/disable function mapping. Check equivalent frequency stability and load capacitance requirements before integration.
