18QHTF21-63.7063-OE

Overview

The 18QHTF21-63.7063-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 63.7063 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 2.0mm x 1.6mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Features integrated enable and disable control functionality
• Utilizes a low-profile surface-mount package design

Applications

• General clock signal generation in electronic circuits
• Timing reference sources for digital systems
• Embedded applications requiring precise frequency standards

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a 63.7063 MHz timing source is required within space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital logic families. Consider the enable/disable feature if power management or clock gating is necessary for the application. The small form factor supports high-density board layouts.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. The manufacturer has decades of experience in Taiwan's crystal industry.
