18QHTF21-24.6945-PD

Oscillators Overview

The 18QHTF21-24.6945-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 24.6945 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby function for power down control. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode capability for power management
• Utilizes a leadless surface-mount package design

Oscillators Applications

• General purpose timing clock generation
• Digital signal processing circuits
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6 mm package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 24.6945 MHz clock signal is required for low-voltage digital applications. The choice depends on the necessity for LVCMOS compatibility and the availability of a 1.8V power supply. Consider the physical space constraints due to the small 2.0x1.6 mm form factor and the need for power-down functionality in battery-operated or energy-efficient designs.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on standard crystal oscillators. The series typically offers various frequencies within a compact SMD package. Mercury Electronics is a specialized supplier of frequency control products, including quartz crystals and oscillators, with a long history in the industry.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with different frequencies, such as 18QHTF21-24.000-PD or 18QHTF21-51.200-PD, provided the frequency difference is acceptable. Cross-brand replacements must match the 24.6945 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6 mm package size.
