18QHTF21-13.800-PD

Overview

The 18QHTF21-13.800-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.8 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode to reduce power consumption during idle periods
• Utilizes a leadless SMD package for space-efficient board integration

Applications

• Battery-powered portable electronic devices
• Low-voltage digital signal processing systems
• Compact consumer electronics requiring precise timing

Procurement Notes

Verify the specific suffix 'PD' indicates the power-down feature as documented. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD no-lead footprint aligns with the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when a 13.8 MHz clock source is required with minimal power draw. The 1.8V operating voltage makes it suitable for modern low-voltage logic families. Consider the standby capability if power management is critical for the application's battery life or thermal constraints.
