18QHTF21-24.589275-PD

Oscillators Overview

The 18QHTF21-24.589275-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 24.589275 MHz with an LVCMOS output logic level. 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 2.0mm x 1.6mm. This component is designed for applications requiring precise clock signals within a small form factor.

Oscillators Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Includes standby mode functionality to reduce power consumption during idle periods
• Utilizes a leadless SMD package design for automated surface-mount assembly

Oscillators Applications

• Clock signal generation for embedded systems
• Timing reference for communication interfaces
• Power management circuits requiring low-voltage operation

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm 4-SMD no-lead package dimensions to prevent mounting issues. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure joint integrity.

Oscillators Selection Notes

Select this component when a precise 24.589275 MHz clock source is required in a minimal space constraint. The LVCMOS output is suitable for standard logic families operating at 1.8V. Consider the standby feature if power efficiency is critical. Compare alternative frequencies if the exact 24.589275 MHz value does not match your system's timing needs. Evaluate the package size against available board real estate.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized 1.8V LVCMOS format. The series is characterized by its small 2.0x1.6mm footprint and leadless construction. Other variants in the series share similar electrical characteristics but differ in output frequency, such as 51.2 MHz or 96.768 MHz options.

Oscillators Replacement Considerations

Direct substitutes must match the 24.589275 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering equivalent frequency control components in identical packages.
