18QHTF21-8.070-OE

Overview

The 18QHTF21-8.070-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 8.07 MHz and utilizes LVCMOS output logic. The device is powered by 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, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output interface
• Enable/Disable control functionality
• Compact 4-SMD No Lead package

Applications

• General purpose clock generation
• Embedded system timing
• Digital signal processing circuits

Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your specific circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the enable/disable pin configuration matches your control logic to prevent unintended operation or excessive power consumption during idle states.

Selection Notes

Select this component when a stable 8.07 MHz reference is required with low-voltage operation. The LVCMOS output ensures compatibility with standard digital logic families. Consider the enable feature if power efficiency is critical. Verify that the 4-SMD package fits within the available PCB footprint constraints.

Part Context

This part belongs to the 18QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'OE' suffix often denotes specific ordering or packaging variations, though functional characteristics remain consistent within the series parameters defined by the manufacturer.

Replacement Considerations

Direct substitutes must match the 8.07 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check datasheets for compatible parts from other manufacturers ensuring identical pinout and electrical specifications.
