18QHTF21-36.57143-PD

Oscillators Overview

The 18QHTF21-36.57143-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 36.57143 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby (power down) function to manage power consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports low-voltage operation with 1.8V supply
• Integrates standby mode for power management
• Provides LVCMOS output signal compatibility

Oscillators Applications

• Digital clock generation
• Data communication interfaces
• Microcontroller system timing

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 4-SMD no-lead package dimensions align with the target PCB footprint. Confirm that the LVCMOS output swing matches the receiving component's input specifications to guarantee signal integrity.

Oscillators Selection Notes

Select this component when a 36.57143 MHz reference is required with low power constraints. The 1.8V operating voltage makes it suitable for modern portable or battery-powered electronics. Consider the standby feature if power efficiency during idle states is a critical design parameter for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same form factor. The series typically provides standard XO options with LVCMOS outputs. The suffix -PD indicates the inclusion of a power-down capability, distinguishing it from non-pd variants in the same package family.

Oscillators Replacement Considerations

Direct substitutes must match the 36.57143 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Alternative parts from other manufacturers require electrical parameter validation to ensure functional equivalence.
