18QHTF21-13.536-PD

Overview

The 18QHTF21-13.536-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.536 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features a standby or power-down function to manage energy consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports standby mode for power management
• Compact surface-mount form factor

Applications

• Battery-powered electronic devices
• Power-sensitive circuit designs
• General timing clock applications

Procurement Notes

Verify the specific frequency suffix matches the required system timing. Confirm the 1.8V supply requirement aligns with the target circuit design. Ensure the 4-SMD package footprint is compatible with the PCB layout. Check for any specific operating temperature range requirements if used in extreme environments.

Selection Notes

Select this model when a precise 13.536 MHz clock signal is needed with minimal power consumption. The LVCMOS interface ensures compatibility with standard digital logic families. The small package size is suitable for space-constrained designs. Consider the standby feature for applications requiring periodic sleep modes.
