18QHTF21-13.5291-OE

Overview

The 18QHTF21-13.5291-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.5291 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component supports an operating temperature range suitable for commercial applications.

Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Features an enable/disable pin for power management control
• Utilizes a leadless surface-mount package for automated assembly

Applications

• Consumer electronics timing circuits
• Communication equipment clock generation
• Embedded system microcontroller interfaces

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout constraints. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 13.5291 MHz reference. The small 2.0x1.6mm package makes it suitable for space-constrained designs. Consider the enable/disable feature if power efficiency during idle states is a priority. Verify that LVCMOS output levels are compatible with the receiving logic inputs.

Part Context

This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronic. The series offers various frequencies within a compact form factor. Mercury Electronic is a Taiwan-based manufacturer specializing in quartz crystals and timing devices. This specific model provides a fixed frequency solution for general-purpose clocking needs.

Replacement Considerations

Direct substitutes must match the 13.5291 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference with other manufacturers offering identical electrical specifications and mechanical dimensions to ensure pinout compatibility.
