18QHTF21-38.700-OE

Oscillators Overview

The 18QHTF21-38.700-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 38.7 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes enable/disable functionality. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control capability
• Surface-mount 4-SMD no lead package design

Oscillators Applications

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

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 4-SMD no lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-profile surface-mount oscillator is required for 38.7 MHz applications. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the enable pin feature if power management or clock gating is necessary within the system architecture. Verify thermal operating range compliance for the intended environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies including 8.64 MHz, 37.888 MHz, 65.3 MHz, and 86.8875 MHz. All variants share similar packaging and electrical characteristics, differing primarily in their nominal operating frequency and specific ordering suffixes.

Oscillators Replacement Considerations

Direct substitutes must match the 38.7 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Cross-reference with other manufacturers offering identical pinout and electrical specifications to ensure functional equivalence without redesigning the host circuitry.
