18QHTF21-14.74566-PD

Oscillators Overview

The 18QHTF21-14.74566-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 14.74566 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down function with standby capability. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode with power-down functionality
• Utilizes a surface-mount 4-SMD no-lead package

Oscillators Applications

• General clock signal generation in electronic circuits
• Digital systems requiring precise timing references
• Embedded devices utilizing low-voltage logic interfaces

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the power-down feature when sourcing replacements. Confirm the operating temperature range and load capacitance requirements against the target design specifications. Ensure the 1.8V supply voltage aligns with the system's power rails to prevent malfunction or damage to the oscillator component.

Oscillators Selection Notes

Select this component for applications requiring a 14.74566 MHz clock source with LVCMOS outputs. The 1.8V supply requirement dictates compatibility with low-voltage digital logic families. The small 2.0x1.6 mm footprint makes it suitable for space-constrained PCB layouts where surface-mount assembly is preferred over through-hole options.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 1.8V LVCMOS format. The series is characterized by its compact SMD packaging and consistent electrical characteristics across different frequency options, facilitating inventory management for multi-frequency designs.

Oscillators Replacement Considerations

Direct substitutes include other 14.74566 MHz XO components with LVCMOS outputs and 1.8V operation. Verify that any replacement matches the 4-SMD no-lead package dimensions and pinout configuration to ensure mechanical and electrical compatibility without redesigning the host circuit board.
