18QHTF21-13.490-PD

Overview

The 18QHTF21-13.490-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.49 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications.

Feature Summary

• LVCMOS output logic interface
• Integrated standby and power-down functionality
• Surface-mount 4-SMD no lead package design

Applications

• General timing clock generation
• Digital signal processing systems
• Embedded controller circuits

Procurement Notes

Verify the specific operating temperature range 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 specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS compatibility. The inclusion of a power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Consider the physical dimensions of the 4-SMD package to ensure it fits within the designated area on the printed circuit board without interfering with adjacent components.

Part Context
