18QHTF21-36.5714-PD

Oscillators Overview

The 18QHTF21-36.5714-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 36.5714 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a standby power-down function for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Includes standby power-down functionality to reduce consumption during idle states
• Utilizes a lead-free surface mount package for automated assembly integration

Oscillators Applications

• General purpose clock signal generation in electronic circuits
• Timing reference sources for digital systems requiring low voltage operation
• Embedded applications necessitating compact surface-mount timing components

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 is stable and within the operational limits specified in the official datasheet. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent soldering defects during assembly.

Oscillators Selection Notes

Select this component when a precise 36.5714 MHz clock source is required in a space-constrained environment. The choice is driven by the need for low-voltage operation at 1.8V and the inclusion of a power-down feature for battery-sensitive or energy-efficient designs. Consider the LVCMOS output compatibility with downstream logic families.

Oscillators Part Context

This model belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series is characterized by its transition from leaded to surface-mount technologies, offering expanded frequency ranges. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from standard continuous-operation variants within the same form factor family.

Oscillators Replacement Considerations

Direct substitutes must match the 36.5714 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent performance metrics such as phase noise and stability if available in competitor datasheets.
