18QHTF21-26.985-OE

Oscillators Overview

The 18QHTF21-26.985-OE is a 26.985 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates on a 1.8V supply voltage and features LVCMOS output logic. The device supports an Enable/Disable function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The unit is designed for operation within a temperature range of -40°C to 85°C.

Oscillators Feature Summary

• Supports active enable/disable control for power optimization
• Utilizes LVCMOS output interface for standard digital compatibility
• Compact surface-mount form factor suitable for space-constrained designs

Oscillators Applications

• Portable consumer electronics requiring low power consumption
• Industrial control systems operating in wide temperature ranges
• Communication modules utilizing standard clock interfaces

Oscillators Procurement Notes

Verify the specific suffix 'OE' indicates the Enable/Disable functionality rather than the 'PD' Power Down variant. Confirm the 1.8V supply requirement matches the target system design. Ensure the 4-SMD no-lead package footprint aligns with the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 26.985 MHz frequency is required with active power control capabilities. Consider the 1.8V operating voltage constraint against the system's available rails. Evaluate the thermal performance requirements against the -40°C to 85°C industrial grade specification for environmental suitability.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The '18' prefix typically denotes the 1.8V supply voltage variant within this product line, distinguishing it from other voltage options available in the broader catalog.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-26.985-PD if power-down functionality is acceptable instead of enable/disable. Other frequencies in the same package may serve as functional replacements if timing requirements differ.
