18QHTF21-38.800-PD

Oscillators Overview

The 18QHTF21-38.800-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 38.8 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down standby function for energy management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface
• Power-down standby capability
• Compact SMD form factor

Oscillators Applications

• General purpose clock generation
• Digital signal processing systems
• Embedded control circuits

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the power-down feature as documented. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD no-lead package footprint aligns with the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a power-saving standby mode. The LVCMOS output is compatible with standard digital logic families. Consider the physical dimensions of the 4-SMD package to ensure adequate space on the printed circuit board for assembly.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, designed for standard frequency reference applications. The manufacturer has extensive experience in quartz crystal production. The model number encodes the frequency and package type, distinguishing it from other variants in the product line.

Oscillators Replacement Considerations

Check for direct substitutes within the same Mercury Electronics series that share the 4-SMD package and 1.8V specification. Verify that any alternative maintains the LVCMOS output logic and similar operating temperature range to ensure functional compatibility.
