18QHTF21-13.531-OE

Overview

The 18QHTF21-13.531-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 13.531 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features an enable/disable control function. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control functionality
• Compact 4-SMD surface-mount package design

Applications

• General clock signal generation in embedded systems
• Timing reference for low-voltage digital circuits
• Consumer electronics requiring precise frequency standards

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly errors during manufacturing.

Selection Notes

Select this component when a low-profile, 1.8V compatible oscillator is required for space-constrained designs. The LVCMOS output is suitable for direct interfacing with standard logic families. Consider the enable pin utility if power management or clock gating is necessary within the application architecture.

Part Context

This part belongs to the QuikXO series from Mercury Electronic, which focuses on fast-delivery CMOS output clock oscillators. The series provides various frequency options within a standardized small form factor, catering to industries needing reliable timing solutions with quick turnaround times.

Replacement Considerations

Direct substitutes include other 13.531 MHz LVCMOS oscillators in 2.0x1.6mm packages with 1.8V operation. Verify equivalent electrical parameters such as phase noise and stability before substitution.
