18QHTF21-20.15411-OE

Oscillators Overview

The 18QHTF21-20.15411-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 20.15411 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Standard XO configuration with LVCMOS output interface
• Integrated enable/disable functionality for power control
• Compact 4-SMD No Lead surface-mount package design

Oscillators Applications

• General purpose digital timing circuits
• Embedded systems requiring stable clock sources
• Consumer electronics with low voltage requirements

Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm exact electrical characteristics and pinout compatibility. Ensure that the 1.8V supply voltage aligns with your system design before procurement. Cross-reference the 4-SMD package dimensions with your PCB footprint library to guarantee mechanical fit. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Oscillators Selection Notes

Select this component when a precise 20.15411 MHz clock signal is required for LVCMOS-compatible logic families. The 1.8V operating voltage makes it suitable for modern low-power portable devices. Consider the enable/disable feature if power conservation during idle states is critical. Evaluate the small form factor against available board space constraints.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. Mercury Electronics is a pioneer in the Taiwan quartz industry with decades of manufacturing experience. The series typically offers various frequencies within a standardized SMD package format.

Oscillators Replacement Considerations

Direct substitutes must match the 20.15411 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify equivalent parts from other manufacturers only if they explicitly state these specifications in their datasheets.
