18QHTF21-27.000625-PD

Oscillators Overview

The 18QHTF21-27.000625-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 27.000625 MHz and utilizes LVCMOS output logic. 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 with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down standby capability
• Utilizes LVCMOS output interface

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Digital communication interfaces

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's specifications. Confirm that the PCB footprint matches the 2.0x1.6mm SMD package dimensions to avoid assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a precise 27.000625 MHz reference is required in space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital logic families. Consider the power-down feature if dynamic power management is critical for the application's battery life or thermal constraints.

Oscillators Part Context

This model belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series is characterized by small form factors and standardized output levels. The 'PD' suffix indicates the inclusion of a power-down control pin, allowing the device to be disabled when not in use to reduce current consumption.

Oscillators Replacement Considerations

Direct replacements must match the 27.000625 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify that substitute components support the same power-down functionality and meet identical temperature range specifications to ensure functional compatibility.
