18QHTF21-26.950-OE

Oscillators Overview

The 18QHTF21-26.950-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 26.95 MHz and utilizes LVCMOS output logic. 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, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Surface-mount 4-SMD no lead package design

Oscillators Applications

• Digital signal processing systems
• Communication equipment timing references
• Embedded system clock generation

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the host system's power rails. Ensure the PCB footprint matches the 4-SMD no lead package dimensions to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling levels. The enable/disable pin allows for dynamic power control in battery-operated devices. Consider the 4-SMD form factor for space-constrained layouts where through-hole components are unsuitable.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent electrical characteristics and packaging. The suffix -OE indicates specific ordering or configuration details defined by the manufacturer for this particular variant within the product line.

Oscillators Replacement Considerations

Direct substitutes must match the 26.95 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify equivalent jitter specifications and enable pin functionality. Cross-reference with other manufacturers offering similar surface-mount XO components with identical pinout and electrical parameters.
