18QHTF21-10.727-OE

Overview

The 18QHTF21-10.727-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.727 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and includes an enable/disable control function 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

• LVCMOS output logic for digital signal compatibility
• Integrated enable and disable functionality for power control
• Compact 4-SMD no-lead surface mount package

Applications

• General clock generation in embedded systems
• Timing reference for low-voltage digital circuits
• Portable electronic devices requiring small form factor oscillators

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 PCB footprint matches the 2.0x1.6mm SMD package dimensions to avoid assembly issues. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a precise 10.727 MHz timing source is needed for LVCMOS-compatible logic families. The integrated enable pin allows for dynamic power management, making it suitable for battery-operated applications. Consider the small 4-SMD package size if space constraints are critical in the design layout.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same physical footprint. The series provides standardized LVCMOS outputs with enable capabilities, ensuring consistency across different timing requirements while maintaining a uniform mechanical profile for board design flexibility.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical package and electrical characteristics but different frequencies, such as 18QHTF21-10.180-OE or 18QHTF21-37.888-OE, provided the frequency difference is acceptable for the application.
