18QHTF21-10.1405-OE

Overview

The 18QHTF21-10.1405-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.1405 MHz and utilizes LVCMOS output logic levels. 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, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS compatible output interface
• Integrated enable/disable functionality
• Compact 4-SMD no-lead package design

Applications

• High-performance digital systems
• Communication equipment clocking
• Embedded system timing references

Procurement Notes

Verify the specific operating temperature range 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 OE suffix with manufacturer documentation to confirm exact electrical tolerances and pinout configurations.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The enable/disable feature makes it suitable for power-sensitive designs. Consider the 4-SMD form factor for space-constrained boards. Verify that the 10.1405 MHz frequency meets the specific timing needs of the target application compared to standard frequencies.

Part Context

This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized small outline package. The -OE suffix likely denotes specific packaging or testing variations defined by the manufacturer for this particular frequency point.

Replacement Considerations

Direct substitutes include other 10.1405 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Check compatibility regarding enable pin logic polarity and output drive strength. Verify thermal characteristics and aging specifications if long-term stability is critical.
