18QHTF21-11.067-PD

Overview

The 18QHTF21-11.067-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 11.067 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features a standby mode to reduce power consumption during idle periods
• Utilizes a small form factor SMD package for surface mount assembly

Applications

• General purpose timing clock generation
• Embedded system synchronization
• Consumer electronics signal processing

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct pinout and electrical characteristics. Confirm that the 'PD' suffix corresponds to the intended power-down functionality as defined in the datasheet. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise 11.067 MHz timing. Consider the 2.0x1.6 mm footprint for space-constrained designs. Ensure the LVCMOS output level matches the input requirements of the connected load circuitry without additional buffering.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 4-SMD package. The series provides consistent mechanical dimensions across different frequency options, simplifying board layout reuse while allowing frequency customization through the model suffix.

Replacement Considerations

Direct substitutes include other 18QHTF21 series variants such as 18QHTF21-51.200-PD or 18QHTF21-96.768-PD if frequency adjustment is acceptable. Verify pin compatibility and voltage levels when considering alternative manufacturers.
