18QHTF21-62.234-OE

Overview

The 18QHTF21-62.234-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind Co Ltd. It operates at a frequency of 62.234 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and features enable/disable control functionality. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm. This component serves as a precise clock source for digital circuits requiring low power consumption and small form factor integration.

Feature Summary

• LVCMOS output interface for direct logic compatibility
• Integrated enable/disable control pin for power management
• Compact 4-SMD no lead surface mount package

Applications

• Portable electronic devices requiring low power operation
• Digital signal processing clock sources
• Communication equipment timing references

Procurement Notes

Verify the specific operating voltage and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply specification aligns with the system power rails. Ensure the 2.0x1.6 mm footprint matches the PCB layout constraints. Check for RoHS compliance status if required by project specifications. Validate the enable/disable pin configuration with the schematic to ensure proper control logic implementation.

Selection Notes

Select this oscillator when a 62.234 MHz frequency is strictly required for the application. Consider the 1.8V supply voltage constraint to ensure compatibility with low-voltage logic families. Evaluate the space limitations on the PCB, as the 4-SMD no lead package offers a small footprint. Assess the need for active control via the enable/disable feature for power-sensitive designs. Compare performance metrics such as phase noise and stability if available in official documentation.

Part Context

This component belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronic. The series typically includes various frequencies and voltage options within a standardized small outline package. Mercury Electronic specializes in quartz crystal and oscillator manufacturing, providing frequency control solutions for consumer and industrial electronics. The OE suffix often denotes specific packaging or tape-and-reel configurations in distributor listings.

Replacement Considerations

Direct substitutes must match the 62.234 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package dimensions. Verify pinout compatibility, particularly the enable/disable function placement. Cross-reference part numbers from other manufacturers offering equivalent specifications in the same form factor. Ensure electrical characteristics such as current consumption and startup time are comparable.
