18QHTF21-13.5575-OE

Overview

The 18QHTF21-13.5575-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.5575 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Integrates enable/disable functionality for efficient power control
• Delivers LVCMOS output signals suitable for digital interfaces
• Utilizes a low-profile surface-mount package design

Applications

• Portable electronic devices requiring low power consumption
• Communication modules utilizing standard clock signals
• Embedded systems needing precise timing references

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 LVCMOS output swing is compatible with the receiving logic inputs. Check for any specific reflow soldering profile recommendations provided in the official datasheet to maintain component integrity during assembly.

Selection Notes

Select this component when a 13.5575 MHz reference is required with minimal footprint constraints. The 1.8V operating voltage makes it suitable for battery-powered or low-voltage logic families. Consider the enable pin if dynamic power saving is necessary. Compare stability specifications against other oscillators in the same series if higher precision is needed for the application environment.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small form-factor oscillators. The series typically offers various frequencies within a standardized 2.0x1.6mm package. The 'OE' suffix indicates the presence of an output enable function, distinguishing it from basic continuous-output variants in the same physical footprint family.

Replacement Considerations

Direct substitutes must match the 13.5575 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that alternative sources provide identical enable/disable functionality and comparable electrical characteristics to ensure seamless integration without circuit modification.
