18QHTF21-23.920-PD

Oscillators Overview

The 18QHTF21-23.920-PD is a crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a frequency of 23.92 MHz with an LVCMOS output logic level. The device functions on a 1.8V supply voltage and features a power-down capability for standby mode. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low voltage operation at 1.8V
• Includes power-down functionality for energy efficiency
• Utilizes LVCMOS output interface

Oscillators Applications

• Digital signal processing systems
• Communication equipment requiring precise timing
• Embedded control circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply rail is stable within the operational range specified in the official datasheet. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly issues.

Oscillators Selection Notes

Select this component when a small form factor is required alongside low power consumption. The 1.8V specification makes it suitable for modern low-voltage digital logic families. Consider the power-down feature if system battery life or thermal management is a priority compared to continuous oscillation models.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature surface-mount oscillators. The series typically offers various standard frequencies and supports both 1.8V and 3.3V operations depending on the suffix. The PD suffix indicates the inclusion of a power-down pin or function.

Oscillators Replacement Considerations

Direct substitutes include other 23.92 MHz XO components in 2.0x1.6mm packages with LVCMOS outputs and 1.8V operation. Verify pin compatibility and electrical specifications such as phase noise and stability before swapping manufacturers.
