18QHTF21-93.440-OE

Overview

The 18QHTF21-93.440-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 93.44 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware enable and disable functionality for power management
• Utilizes a lead-free surface-mount package design

Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific suffix OE against the manufacturer's current documentation to confirm availability and exact electrical tolerances. Ensure the 1.8V supply requirement aligns with the target system design. Confirm the 4-SMD no-lead footprint matches the PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The small 2.0x1.6 mm form factor makes it suitable for space-constrained designs. Consider the enable pin capability if dynamic power saving or clock gating is necessary for the application architecture.

Part Context

This part belongs to the Mercury Electronics SMD oscillator series designed for high-frequency stability. The 18QHTF21 series typically offers standard performance levels for general electronic applications. Mercury Electronics has established itself as a pioneer in quartz crystal manufacturing, providing various frequency control solutions including oscillators and filters.

Replacement Considerations

Check for direct substitutes within the 18QHTF21 family sharing the same 93.44 MHz frequency and 1.8V supply. Verify that alternative parts maintain identical LVCMOS logic levels and physical footprint dimensions to ensure mechanical compatibility without redesigning the host board.
