18QHTF21-10.026-OE

Overview

The 18QHTF21-10.026-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 10.026 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a 1.8V supply voltage. It features an integrated Enable/Disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated Enable/Disable functionality for power management
• Compact 4-SMD No Lead surface-mount package design

Applications

• General clock signal generation in electronic circuits
• Timing reference for low-voltage digital systems
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet for your application environment.

Selection Notes

Select this component when a precise 10.026 MHz timing source is required for LVCMOS-compatible digital logic. The choice is driven by the need for low-voltage operation at 1.8V and the integration of enable/disable controls. Consider the small form factor of the 4-SMD package for space-constrained designs. Evaluate the manufacturer's reliability standards for frequency control products.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series typically offers various standard frequencies with LVCMOS outputs.
