S218025T-4.000-R

Oscillators Overview

The S218025T-4.000-R is a standard crystal oscillator (XO) manufactured by Aker Technology Corp, operating at a nominal frequency of 4 MHz. It utilizes HCMOS output logic and functions with a supply voltage of 1.8V. The device features an enable/disable control function for power management. It is housed in a compact 4-SMD, no lead package suitable for surface-mount applications.

Oscillators Feature Summary

• HCMOS output interface for digital signal compatibility
• Integrated enable and disable control functionality
• Ultra-miniature 4-SMD surface-mount package design

Oscillators Applications

• Microprocessor-based system clock generation
• Telecommunications equipment timing circuits
• Data storage and delivery systems
• Computer product internal timing references

Oscillators Procurement Notes

Verify the specific ordering suffix to confirm the exact frequency tolerance and load capacitance requirements for your design. Ensure the 1.8V supply voltage aligns with your target circuit's power rails. Confirm that the HCMOS output swing is compatible with downstream logic inputs. Check the enable pin configuration against your system's power sequencing strategy to ensure proper operation during startup and shutdown phases.

Oscillators Selection Notes

Select this component when a low-voltage, small-footprint oscillator is required for 4 MHz applications. The HCMOS output is suitable for general-purpose digital logic interfacing. Consider the enable feature if dynamic power saving is necessary. Verify that the 4-SMD package dimensions fit within the available PCB space constraints compared to larger through-hole or alternative SMD packages.
