18QHTF21-23.000-PD

Oscillators Overview

The 18QHTF21-23.000-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 23.0 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down standby function to reduce consumption. 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 standby capability
• Utilizes LVCMOS output interface

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Portable electronic devices requiring low power

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply rail is stable and within the specified operating range. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors.

Oscillators Selection Notes

Select this component when a precise 23.0 MHz reference is required in space-constrained designs. The choice is driven by the need for low voltage compatibility and active power management via the standby pin. Consider the small form factor for high-density board layouts.

Oscillators Part Context

This part belongs to the Mercury Electronic XO series, which provides frequency control solutions. The manufacturer has produced quartz crystals and oscillators since 1973. This specific model represents a standard clock oscillator variant optimized for modern low-power digital applications.

Oscillators Replacement Considerations

Check for direct substitutes with identical 23.0 MHz frequency, 1.8V supply, and LVCMOS output. Verify package compatibility for the 2.0x1.6mm SMD footprint. Ensure thermal and electrical characteristics match the original design specifications.
