18QHTF21-13.482-PD

Overview

The 18QHTF21-13.482-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.482 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component is suitable for applications requiring precise timing signals within low-power electronic systems.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode functionality for power management
• Utilizes a leadless surface-mount package design

Applications

• General purpose timing circuits
• Low-power embedded systems
• Digital signal processing interfaces

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure reliable assembly and long-term performance stability.

Selection Notes

Select this component when a 13.482 MHz clock signal is required with LVCMOS compatibility. Consider the 1.8V operating voltage and standby feature for power-sensitive designs. Evaluate the 2.0x1.6mm package size against available board space. Compare performance metrics such as phase noise and jitter if high-frequency stability is critical for your specific application environment.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics Ind. Co. Ltd, which offers various frequency options within the same physical package. The series includes models like 18QHTF21-51.200-PD and 18QHTF21-15.700-PD, sharing identical electrical characteristics and form factors but differing in output frequency. This consistency allows for flexible design reuse across different timing requirements.

Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with matching frequencies, such as 18QHTF21-13.482 from other manufacturers if pin-compatible. Verify equivalent specifications for frequency stability, output drive strength, and operating temperature range before substitution.
