18QHTF21-36.670-OE

Oscillators Overview

The 18QHTF21-36.670-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 36.67 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features an enable/disable control function. 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

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

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet to guarantee reliability under your environmental conditions.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature allows for power management in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained designs. Verify that the 36.67 MHz frequency meets the specific timing needs of the target application without requiring external dividers or multipliers.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which includes various frequencies and packages. The '18' prefix likely indicates the 1.8V supply voltage, while 'QHTF21' denotes the specific package and performance class. Similar models in the series include variants like 18QHTF21-36.760-OE and 18QHTF21-37.888-OE, differing primarily in output frequency.

Oscillators Replacement Considerations

Direct substitutes must match the 36.67 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Models such as 18QHTF21-36.760-OE are similar but have different frequencies. Cross-reference with other manufacturers offering 4-pin SMD oscillators with identical electrical specifications and pinout configurations.
