18QHTF21-11.000-OE

Overview

The 18QHTF21-11.000-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 11.000 MHz and utilizes LVCMOS output logic levels. The component requires 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 with dimensions of 2.0mm x 1.6mm, suitable for surface-mount applications.

Feature Summary

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

Applications

• Timing and clock signal generation in electronic devices
• Low-power consumer electronics
• Embedded systems requiring precise frequency references

Procurement Notes

Verify the specific ordering suffix to confirm the output load and tolerance specifications. Ensure the supply voltage matches the 1.8V requirement. Confirm the package footprint aligns with the 2.0x1.6mm SMD design. Check for availability of the OE (Enable/Disable) variant if power control is required.

Selection Notes

Select this component when a low-voltage 1.8V operation is necessary. The LVCMOS output is appropriate for standard digital interfaces. Consider the small form factor for space-constrained designs. Verify that the enable/disable feature meets system power management needs.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystals and oscillators. The series offers various frequencies and voltage options. Mercury has been a supplier since 1973, focusing on timing components for global markets.

Replacement Considerations

Check for direct substitutes within the same series, such as 18QHTF21-11.000-PD, noting potential differences in output enable functionality. Verify electrical parameters and package dimensions before substitution.
