18QHTF21-13.486-PD

Overview

The 18QHTF21-13.486-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.486 MHz with LVCMOS output logic. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports standby mode for power management
• LVCMOS output interface
• Compact surface-mount package

Applications

• General electronic timing circuits
• Digital signal processing systems
• Communication equipment

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure 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 to avoid assembly issues during manufacturing.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small form factor. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the standby feature if power efficiency during idle periods is a critical design constraint for the application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal oscillators. The series offers various frequencies within a standardized 2.0x1.6 mm package. Mercury Electronics has been a supplier of frequency control products since 1973, focusing on reliability in timing applications.

Replacement Considerations

Direct substitutes include other 13.486 MHz XO models from Mercury Electronics with identical 1.8V LVCMOS specifications and 4-SMD packages. Cross-brand replacements must match the voltage, output type, and physical dimensions to ensure compatibility.
