18QHTF21-4.604-OE

Oscillators Overview

The 18QHTF21-4.604-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 4.604 MHz and utilizes LVCMOS output logic levels. The component is designed for low-voltage applications, functioning with a supply voltage of 1.8V. It features an enable/disable control pin for power management flexibility. The device is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

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

Oscillators Applications

• Embedded systems requiring precise timing references
• Industrial control equipment clock sources
• Consumer electronics with low-power requirements

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 4.604 MHz specification. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout. Check datasheet specifications for operating temperature range and load capacitance requirements before integration.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is mandatory. The LVCMOS output is suitable for standard digital interfaces. Consider the enable/disable feature if power conservation during idle states is required. Verify that the 4.604 MHz frequency meets the system clock needs. The small form factor aids in dense board designs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronic. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes specific packaging or tape-and-reel configuration. Mercury Electronic specializes in quartz crystals and timing components, providing reliable frequency control solutions for global markets.

Oscillators Replacement Considerations

Direct substitutes must match the 4.604 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical parameters such as jitter and stability. Alternative parts from other manufacturers require careful evaluation of thermal and mechanical specifications.
