S51805T-27.000-X-R

Oscillators Overview

The S51805T-27.000-X-R is a surface-mount crystal oscillator (XO) manufactured by Aker Technology Corp, operating at a nominal frequency of 27 MHz. It utilizes HCMOS output logic and supports a supply voltage range from 1.8V to 3.3V. The device features a frequency stability of ±50 ppm and includes an enable/disable control function. Packaged in a compact 4-SMD, no-lead form factor with dimensions of 5mm x 3.2mm x 0.95mm, it is designed for surface mounting. The component operates within a temperature range of -40°C to +85°C and complies with RoHS standards.

Oscillators Feature Summary

• Integrates enable and disable control functionality for power management
• Delivers standard HCMOS output signals
• Utilizes a compact four-terminal surface-mount package

Oscillators Applications

• Embedded system clock generation
• Microcontroller timing sources
• General-purpose digital circuit synchronization

Oscillators Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging configuration as documented by distributors. Confirm that the enable/disable pinout matches the target schematic design requirements. Ensure the 1.8V to 3.3V supply voltage compatibility aligns with the host system's power rails before integration.

Oscillators Selection Notes

Select this model when a 27 MHz reference signal with HCMOS levels is required for space-constrained designs. The enable/disable feature makes it suitable for battery-powered applications requiring power optimization. Verify that the ±50 ppm stability meets the system's jitter and timing tolerance specifications.

Oscillators Part Context

This component belongs to the S5 series of surface-mount oscillators from Aker Technology. The series offers various frequencies and packages, providing standardized solutions for frequency control needs. The S51805T variant specifically denotes the 27 MHz frequency option within this family.

Oscillators Replacement Considerations

Direct substitutes include other 27 MHz HCMOS XO components with compatible 4-SMD footprints and similar voltage ranges. Cross-reference part numbers such as S51805T-27.000-X-M for alternative packaging options if reel availability is constrained.
