18QHTF21-23.1481-PD

Oscillators Overview

The 18QHTF21-23.1481-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 23.1481 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. The component is designed for applications requiring precise clock signals within a small form factor.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features a standby mode to reduce power consumption during idle periods
• Utilizes a surface-mount 4-pin no-lead package for automated assembly

Oscillators Applications

• Embedded systems requiring precise timing references
• Communication modules needing stable clock sources
• Portable electronic devices constrained by size and power limits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational specifications. Confirm that the PCB footprint matches the 2.0x1.6mm SMD package dimensions to avoid assembly issues. Cross-reference the datasheet for any specific handling precautions related to the no-lead package type.

Oscillators Selection Notes

Select this component when a low-profile, low-voltage oscillator is required for high-density designs. The LVCMOS output ensures direct interfacing with most digital logic families without additional level shifting. Consider the standby feature if power efficiency is critical for battery-operated applications. Verify that the operating temperature range aligns with the environmental conditions of the end product.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized 2.0x1.6mm package. The series is characterized by its compact size and low power consumption, making it suitable for modern miniaturized electronics. The 'PD' suffix typically indicates the inclusion of a power-down capability, distinguishing it from continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 23.1481 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Check for equivalent standby functionality and identical pinout configurations. Verify that alternative manufacturers offer compatible frequency stability and phase noise specifications to ensure system performance remains unaffected.
