18QHTF21-33.1766-PD

Oscillators Overview

The 18QHTF21-33.1766-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 33.1766 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. A key functional characteristic is the inclusion of a standby mode, which 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 processes.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby functionality for power-down control
• Operates on a 1.8V supply voltage rail

Oscillators Applications

• Digital signal processing systems requiring precise timing

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power architecture. Confirm that the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Check for any specific handling instructions regarding electrostatic discharge protection during storage and installation.

Oscillators Selection Notes

Select this component when a stable 33.1766 MHz reference is required for LVCMOS-compatible circuits. Consider the 1.8V operating voltage if your system uses low-voltage logic families. The standby feature makes it suitable for battery-operated or power-sensitive devices. Evaluate the 4-SMD package size against available board space compared to other oscillator form factors.

Oscillators Part Context
