18QHTF21-34.752-OE

Oscillators Overview

The 18QHTF21-34.752-OE is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 34.752 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes hardware enable/disable control functionality
• Utilizes a leadless 4-SMD surface-mount package design

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for low-voltage digital circuits
• Consumer electronics requiring precise frequency standards

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 enable/disable pin configuration matches the host controller's GPIO capabilities to guarantee proper operational control during system initialization.

Oscillators Selection Notes

Select this component when a stable 34.752 MHz clock source is required for 1.8V logic families. Consider the enable/disable feature if power management or clock gating is necessary within the application. Evaluate the 4-SMD package dimensions against available PCB real estate constraints to ensure compatibility with the assembly process.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency oscillators. The model number indicates a 1.8V operating voltage and a specific frequency variant. It is distinct from differential oscillators or crystals within the same manufacturer portfolio, serving as a single-ended clock solution for standard digital interfaces.

Oscillators Replacement Considerations

Direct substitutes must match the 34.752 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 before substitution. Consult official distributor databases for cross-reference lists provided by Mercury Electronics.
