18QHTF21-14.48536-PD

Oscillators Overview

The 18QHTF21-14.48536-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 14.48536 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down feature for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

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

Oscillators Applications

• Digital signal processing clocking
• Communication equipment timing
• Embedded system synchronization

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 rail stability meets the oscillator's operational specifications. Ensure the PCB layout accommodates the 4-SMD no-lead footprint dimensions accurately to maintain signal integrity and thermal performance during assembly.

Oscillators Selection Notes

Select this component when a precise 14.48536 MHz reference is required for LVCMOS interfaces. Consider the 1.8V operating voltage constraint and the necessity for power-down functionality. Evaluate the physical space constraints against the 2.0x1.6 mm package size to ensure mechanical fit within the final assembly design.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, designed for surface-mount applications. The series offers various frequencies with standardized LVCMOS outputs. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical pinouts and electrical characteristics but different frequencies, such as 18QHTF21-51.200-PD or 18QHTF21-6.770-PD, provided the frequency difference is acceptable for the application.
