18QHTF53-25.0625-PD

Oscillators Overview

The 18QHTF53-25.0625-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 25.0625 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 5.0 mm length by 3.2 mm width.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby power-down functionality
• Provides LVCMOS signal output

Oscillators Applications

• General clock generation in electronic circuits
• Digital signal processing systems
• Communication equipment requiring precise timing

Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your specific circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's specifications to maintain performance. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to ensure proper assembly and electrical connection.

Oscillators Selection Notes

Select this component when a 25.0625 MHz reference is required with low power consumption capabilities. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the 1.8V operating voltage constraint and verify that the system power budget supports this level. The small form factor makes it suitable for space-constrained designs where standard leaded packages cannot fit.

Oscillators Part Context

This model belongs to the Mercury Electronics SMD Oscillator series, specifically designed for surface-mount applications. The 'PD' suffix indicates the inclusion of a power-down control feature, allowing the device to be disabled when not in use. This series is part of the manufacturer's broader portfolio of quartz-based frequency control products established since 1973.

Oscillators Replacement Considerations

Direct substitutes must match the 25.0625 MHz frequency, 1.8V supply, LVCMOS output, and 5.0x3.2mm package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar SMD oscillators only if they explicitly confirm identical electrical parameters and mechanical dimensions.
