18QHTF21-38.00053-PD

Oscillators Overview

The 18QHTF21-38.00053-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 38.00053 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features a Standby function that allows for power-down capability to reduce energy consumption when the oscillator is not in active use. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• LVCMOS output logic interface
• Integrated standby mode for power management
• Compact no-lead SMD package

Oscillators Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded electronics control circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions specified in the official datasheet to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 38.00053 MHz reference is required with low power consumption capabilities. The LVCMOS output ensures compatibility with standard digital logic families operating at 1.8V. Consider the standby feature if power efficiency is critical. Verify that the operating temperature range meets the environmental conditions of the intended deployment scenario.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small form factor. The 'PD' suffix indicates the inclusion of a power-down or standby pin functionality, distinguishing it from continuous-operation variants within the same physical package family.

Oscillators Replacement Considerations

Direct replacements must match the 38.00053 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical specifications such as phase noise and jitter if available in public documentation.
