18QHTF21-28.1261-OE

Oscillators Overview

The 18QHTF21-28.1261-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 28.1261 MHz with an LVCMOS output interface. The device functions on a 1.8V supply voltage and includes an Enable/Disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. The component supports an operating temperature range of -40°C to 85°C and offers a frequency stability of ±50ppm.

Oscillators Feature Summary

• LVCMOS output signal compatibility
• Integrated enable/disable functionality
• Compact surface-mount packaging

Oscillators Applications

• Embedded systems requiring precise timing
• Consumer electronics devices
• Industrial control modules

Oscillators Procurement Notes

Verify the specific suffix (OE) against official datasheets to confirm the presence of the enable pin, as this variant differs from standard outputs. Ensure the 1.8V supply requirement aligns with the target system design. Confirm the 2.0x1.6mm footprint matches the PCB layout constraints. Cross-reference the ±50ppm stability specification with application requirements before finalizing procurement decisions.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside an enable control feature. The small 4-SMD form factor suits space-constrained designs. Verify that the ±50ppm stability meets the system's clock accuracy needs. Consider the -40°C to 85°C temperature range for environmental suitability. Compare against other Mercury oscillators if different frequencies or packages are needed.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'OE' suffix indicates the inclusion of an enable pin, distinguishing it from basic output variants. These components are designed for general-purpose timing applications in modern electronic circuits.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with matching 28.1261 MHz frequency and OE suffix. Verify pinout compatibility and electrical specifications before substitution. Alternative manufacturers may offer similar LVCMOS oscillators but require full parameter validation.
