18QHTF21-33.880-OE

Oscillators Overview

The 18QHTF21-33.880-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 33.88 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals in electronic circuits.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated enable and disable control pin
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for microcontrollers and processors
• Digital signal processing equipment synchronization

Oscillators Procurement Notes

Verify the specific suffix OE against the manufacturer's current datasheet to confirm availability and exact electrical tolerances. Ensure the 1.8V supply requirement matches the target circuit design. Confirm the 4-SMD package dimensions align with the PCB footprint specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS signaling standards. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small form factor of the 4-SMD package for space-constrained layouts compared to larger through-hole alternatives.

Oscillators Part Context

Mercury Electronics Ind. Co. Ltd specializes in quartz crystals and oscillators, including TCXO and VCTCXO types. This model belongs to their standard XO series, providing reliable frequency control solutions. The company has decades of experience in Taiwan's frequency control industry, focusing on precision timing components for various electronic applications.

Oscillators Replacement Considerations

Check for direct substitutes within the same Mercury Electronics series with matching 33.88 MHz frequency and 1.8V supply. Verify that alternative packages maintain the 4-SMD no-lead configuration. Ensure output logic remains LVCMOS to guarantee compatibility with existing digital interfaces without additional level shifting.
