18QHTF21-67.108865-OE

Overview

The 18QHTF21-67.108865-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 67.108865 MHz and utilizes LVCMOS output logic levels. The device supports an enable/disable control function and is designed for operation with a supply voltage of 2.5V. It is housed in a compact 4-SMD, No Lead package with dimensions of 3.2x2.5mm, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports enable/disable functionality for power management
• Utilizes LVCMOS output interface for digital compatibility
• Compact 4-SMD no-lead surface mount package design

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Mercury Electronics documentation to ensure correct voltage and package configuration. Confirm that the OE suffix aligns with the required enable/disable feature set. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components. Ensure the 2.5V supply requirement matches the target application design constraints before procurement.

Selection Notes

Select this component when a 67.108865 MHz clock source is required with low-profile surface-mount packaging. Consider the 2.5V operating voltage and LVCMOS output compatibility with downstream logic circuits. The enable/disable feature offers flexibility for power-sensitive designs. Evaluate the 3.2x2.5mm footprint against available PCB space constraints during the layout phase.
