18QHTF21-13.1072-PD

Overview

The 18QHTF21-13.1072-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.1072 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down mode capability. 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 or power-down functionality to reduce consumption
• Utilizes quartz-based technology for stable frequency generation

Applications

• General clock signal generation in electronic circuits
• Digital systems requiring precise timing references
• Embedded devices utilizing low-voltage logic interfaces

Procurement Notes

Verify the specific frequency tolerance 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 dimensions fit within your PCB footprint constraints. Cross-reference the part number suffix to confirm the exact variant matches your application needs.

Selection Notes

Select this component when a 13.1072 MHz reference is required with LVCMOS outputs. Consider the 1.8V operating voltage for compatibility with modern low-power digital logic families. Evaluate the need for standby modes if power efficiency is critical. Compare package size against available board space to ensure mechanical fit.

Part Context

This model belongs to the Mercury Electronics XO series, which includes various frequencies such as 51.2 MHz and 6 MHz. These oscillators share common packaging and logic characteristics but differ in frequency specifications. The product line emphasizes quartz-based stability for industrial and commercial applications.

Replacement Considerations

Direct substitutes include other 13.1072 MHz LVCMOS oscillators from Mercury Electronics with identical 4-SMD no-lead packages. Verify equivalent electrical parameters such as supply voltage and output swing before substitution.
