18QHTF21-10.0587-PD

Overview

The 18QHTF21-10.0587-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.0587 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby mode that supports power-down functionality to minimize energy consumption during idle periods. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes. This configuration ensures reliable performance in space-constrained electronic designs requiring precise clock signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode with power-down capability for energy efficiency
• Utilizes a lead-free 4-SMD surface-mount package design

Applications

• Battery-powered portable electronic devices
• General-purpose digital circuit clocking
• Embedded systems requiring low-power oscillators

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics for detailed electrical characteristics and reliability data prior to finalizing procurement decisions.

Selection Notes

Select this component when a 10.0587 MHz clock signal is required with strict power budget constraints. The 1.8V operation makes it suitable for modern low-voltage logic families. Consider the standby feature if power management is critical. Evaluate the 4-SMD package size against available board real estate. Compare performance metrics such as phase noise and stability if high-precision timing is necessary for the application.
