18QHTF21-23.4375-PD

Oscillators Overview

The 18QHTF21-23.4375-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 23.4375 MHz and utilizes LVCMOS output logic. The device is designed for low voltage applications, requiring a 1.8V supply. It features a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm. A key functional characteristic is the inclusion of a standby or power-down mode to reduce energy consumption when the oscillator is not actively in use.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby (power down) functionality for energy management
• Utilizes a compact 4-SMD no lead surface-mount package

Oscillators Applications

• Digital signal processing circuits
• Communication equipment timing references
• Embedded system clock generation

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 23.4375 MHz operation. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no lead package footprint corresponds to the PCB layout specifications. Check for any specific handling requirements associated with the surface-mount technology used in this component series.

Oscillators Selection Notes

Select this component when a precise 23.4375 MHz reference is required for LVCMOS-based digital systems. The choice is driven by the need for a low-voltage 1.8V operation and the space constraints addressed by the small 2.0x1.6 mm package. Consider the power-down feature if battery life or thermal management is a critical design parameter for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics Ind. Co. Ltd, which offers various frequencies within the same physical form factor. The series typically includes options for different supply voltages and output types, but this specific model is defined by its 23.4375 MHz frequency and 1.8V LVCMOS configuration.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinout and package dimensions but different frequency suffixes, provided the electrical parameters match. Cross-referencing with similar 4-SMD no lead oscillators from other manufacturers requires verifying voltage levels and output logic compatibility.
