18QHTF21-62.500-OE

Overview

The 18QHTF21-62.500-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 62.500 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Standard XO configuration with LVCMOS output interface
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system 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 4-SMD footprint matches your PCB layout constraints. Cross-reference the datasheet for operating temperature ranges to guarantee reliability under your specific environmental conditions.

Selection Notes

Select this component when a 62.500 MHz reference is required with low voltage operation. Consider the LVCMOS compatibility with downstream digital logic. Evaluate the need for active enable/disable features versus always-on oscillators. Compare package dimensions against available board space. Verify that the manufacturer's specifications meet your phase noise and stability requirements.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd., a Taiwanese manufacturer specializing in frequency control products since 1973. The series includes various frequencies such as 6.76438 MHz, 37.888 MHz, and 86.8875 MHz, all sharing similar package and electrical characteristics like 1.8V operation and LVCMOS outputs.

Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with different frequencies if the exact 62.500 MHz is not critical. Check for equivalent LVCMOS oscillators from other manufacturers with identical 4-SMD footprints and 1.8V supply requirements. Ensure pinout compatibility and electrical parameters match before substitution.
