18QHTF21-24.1225-PD

Oscillators Overview

The 18QHTF21-24.1225-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 24.1225 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby (power down) feature for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby mode for power reduction
• Provides LVCMOS signal output

Oscillators Applications

• General clock generation in electronic circuits
• Timing reference for digital systems
• Embedded system synchronization

Oscillators Procurement Notes

Verify the exact operating temperature range and load capacitance requirements against the specific application design before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 24.1225 MHz timing source is required within space-constrained designs. The choice is driven by the need for low-power consumption via the standby function and compatibility with 1.8V logic levels. Consider the small 2.0x1.6mm form factor if board real estate is limited compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within similar physical footprints. The 'PD' suffix indicates the inclusion of a power-down control capability, distinguishing it from continuously running variants in the same family.

Oscillators Replacement Considerations

Direct substitutes include other 24.1225 MHz LVCMOS oscillators with identical 1.8V supply and 4-SMD no-lead packaging. Verify pinout compatibility and electrical specifications such as jitter and phase noise before swapping manufacturers.
