S218025T-25.000-R

Oscillators Overview

The S218025T-25.000-R is a surface-mount HCMOS crystal oscillator manufactured by Aker Technology Corp. It operates at a nominal frequency of 25.000 MHz with a load capacitance of 15 pF. The device supports a supply voltage range of 1.8V to 3.3V, typically utilizing 1.8V or 2.5V levels. It features an enable/disable function and tri-state output capability. The unit is housed in a 4-SMD package with no lead construction.

Oscillators Feature Summary

• HCMOS output interface for standard digital logic compatibility
• Integrated enable and disable control functionality
• Tri-state output capability for bus sharing applications
• Surface-mount design with lead-free compliant packaging

Oscillators Applications

• General purpose clock signal generation in embedded systems
• Timing reference for microprocessor-based applications
• Clock input for telecommunications equipment
• Frequency source for data storage and delivery devices

Oscillators Procurement Notes

Verify the specific supply voltage requirement (1.8V vs 3.3V) against the target circuit design before procurement. Confirm that the 4-SMD footprint matches the PCB layout constraints. Ensure the enable pin logic level is compatible with the controlling GPIO. Check RoHS compliance status if required by environmental regulations. Validate the operating temperature range suitability for the intended application environment.

Oscillators Selection Notes

Select this component when a low-profile surface-mount HCMOS oscillator is required for 25 MHz timing. Consider the enable feature if power management during idle states is necessary. Compare against other Aker models like the S218025T-20.000-R if different frequencies are needed. Ensure the load capacitance specification aligns with the receiving circuit's input requirements. Evaluate thermal performance within the specified operating temperature limits.

Oscillators Part Context

This part belongs to Aker Technology's series of ultra-miniature CMOS and differential XOs. It complements their broader portfolio of TCXOs and VCXOs which offer tighter stability. The product line targets automotive, computer, and instrumentation markets. Aker provides these solutions for global electronics manufacturing.
