SG-8018CE 2.2240M-TJHPA0

Oscillators Overview

The SG-8018CE 2.2240M-TJHPA0 is a standard CMOS clock oscillator from the Epson SG-8018 series, manufactured by Epson Timing. It operates at a fixed frequency of 2.224 MHz with a base crystal resonator. The device supports a supply voltage range of 1.62V to 3.63V and features an Enable/Disable control function. It offers a frequency stability of +/-50 PPM and functions within an industrial temperature range of -40°C to +105°C. The component is housed in a 4-SMD, No Lead package.

Oscillators Feature Summary

• Integrated Enable/Disable functionality for power management control
• Industrial-grade temperature rating for reliable operation in harsh environments
• CMOS output signal compatible with standard digital logic interfaces

Oscillators Applications

• Embedded systems requiring precise timing references
• Industrial control equipment operating in extreme temperatures
• Communication modules utilizing standard CMOS clock inputs

Oscillators Procurement Notes

Verify that the specific suffix TJHPA0 matches the required reel or cut tape packaging configuration for automated assembly lines. Confirm the enable/disable pinout requirements against the schematic design. Ensure the supply voltage rails align with the 1.62V to 3.63V operational window to prevent malfunction. Cross-reference the lead time estimates provided by authorized distributors, as production cycles may vary based on current demand and manufacturing schedules.

Oscillators Selection Notes

Select this model when a low-frequency 2.224 MHz reference is required alongside active power control capabilities. The wide voltage tolerance accommodates various logic families without level shifting. Consider the +/-50 PPM stability sufficient for general synchronous data transmission. The no-lead package facilitates surface-mount placement, reducing mechanical stress compared to through-hole alternatives.

Oscillators Part Context

This component belongs to the SG-8018 family of precision oscillators designed for compact electronic applications. The CE variant specifically denotes the inclusion of an enable/disable feature, distinguishing it from continuously running models like the CG or CB series. This family utilizes high-quality crystal resonators to ensure long-term frequency stability across the specified industrial temperature range.

Oscillators Replacement Considerations

Direct substitutes include other SG-8018 variants with matching frequencies and packages, such as SG-8018CG or SG-8018CB models, though these lack the enable/disable feature. Verify pin compatibility and electrical characteristics before swapping between series members to ensure functional equivalence in the target circuit.
