18QHTF21-19.9998-OE

Oscillators Overview

The 18QHTF21-19.9998-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 19.9998 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning at 1.8V supply voltage. It features an enable/disable control pin for power management flexibility. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm, suitable for surface-mount assembly in space-constrained electronic designs.

Oscillators Feature Summary

• LVCMOS output interface for digital compatibility
• Integrated enable/disable functionality for power optimization
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Industrial electronics timing circuits
• Consumer electronics clock sources
• Embedded systems requiring precise frequency reference

Oscillators Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the enable/disable feature configuration. Ensure the 1.8V supply requirement aligns with target system voltage rails. Confirm package footprint compatibility during PCB layout finalization. Request updated datasheets directly from the manufacturer or authorized distributors to validate current production status and RoHS compliance details before procurement.

Oscillators Selection Notes

Select this component when a 19.9998 MHz clock signal is required with low voltage operation. The enable/disable pin allows for dynamic power control, making it suitable for battery-operated devices. The small 2.0x1.6mm footprint aids in high-density board layouts. Compare against other frequencies in the 18QHTF21 series if different timing standards are needed.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequency options within a standardized 4-SMD package. The 'OE' suffix typically denotes specific operational characteristics such as the enable pin presence, distinguishing it from standard variants without control inputs.

Oscillators Replacement Considerations

Direct substitutes must match the 19.9998 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify that any alternative part includes the enable/disable function if required by the design. Cross-reference pinouts and electrical specifications with the original datasheet to ensure functional equivalence.
