18QHTF21-7.168-OE

Overview

The 18QHTF21-7.168-OE is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.168 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• LVCMOS output interface for standard digital compatibility
• Integrated enable and disable functionality
• Compact surface-mount package design

Applications

• General purpose timing circuits
• Embedded system clock sources
• Digital signal processing interfaces

Procurement Notes

Verify the specific ordering suffix to ensure correct frequency tolerance and temperature range specifications. Confirm that the 1.8V supply voltage aligns with the target system power rails. Ensure the LVCMOS output level matches the receiving logic input requirements. Check for any specific RoHS or environmental compliance documentation required for the project.

Selection Notes

Select this component when a low-voltage 1.8V operation is required for space-constrained designs. The LVCMOS output is suitable for standard digital logic families. Consider the small 2.0x1.6 mm footprint for high-density PCB layouts. Verify that the enable pin functionality meets the power management needs of the application.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The manufacturer has decades of experience in Taiwan's crystal industry. This series offers various frequencies within a standardized small outline package format.

Replacement Considerations

Direct substitutes must match the 7.168 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify electrical parameters such as load capacitance and drive level before substitution.
