S31805T-26.000-R

Oscillators Overview

The S31805T-26.000-R is a standard frequency crystal oscillator (XO) manufactured by Aker Technology Corp. It operates at a nominal frequency of 26.0000 MHz with a frequency stability of ±50 ppm and an aging rate of ±5 ppm per year. The device utilizes HCMOS output levels and requires a load capacitance of 15 pF. It functions on a single 1.8V supply voltage and features an enable/disable control pin. The component is housed in a compact 4-SMD, no-lead surface-mount package and is supplied in tape and reel packaging for automated assembly processes.

Oscillators Feature Summary

• HCMOS output signal compatibility
• Active enable/disable control functionality
• Surface-mount design for automated placement

Oscillators Applications

• General purpose digital clock generation
• Microprocessor timing references
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific suffix requirements against the official Aker Technology datasheet to ensure correct packaging and tolerance specifications. Confirm that the 1.8V operating voltage aligns with the target system power rails before finalizing procurement orders. Ensure the HCMOS output level is compatible with the receiving logic inputs to prevent signal integrity issues.

Oscillators Selection Notes

Select this component when a 26 MHz reference is required with low voltage operation. The HCMOS output provides robust noise immunity compared to lower drive levels. Consider the ±50 ppm stability requirement against the system's jitter budget. The enable pin allows for power management strategies in battery-operated devices requiring periodic clock activation.

Oscillators Part Context

This part belongs to the S31805T series of precision crystal oscillators from Aker Technology. The series offers various standard frequencies tailored for embedded applications. The manufacturer specializes in frequency control products established since 1990, providing solutions for global electronics industries requiring reliable timing sources.

Oscillators Replacement Considerations

Direct substitutes include other S31805T variants with different frequencies such as S31805T-25.000-X-R or S31805T-30.000-X-R if frequency adjustment is permissible. Cross-brand replacements must match the 4-SMD footprint, 1.8V supply, and HCMOS output characteristics to maintain board compatibility.
