18QHTF21-3.584-PD

Oscillators Overview

The Mercury Electronics Ind. Co. Ltd model 18QHTF21-3.584-PD is a standard crystal oscillator (XO) designed for precision timing applications. It operates at a nominal frequency of 3.584 MHz and utilizes LVCMOS output logic levels. The device is engineered to function with a supply voltage of 1.8V and includes a standby or power-down feature for energy management. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Supports standby mode to reduce power consumption during idle periods
• Utilizes a leadless SMD package for automated surface-mount placement

Oscillators Applications

• General-purpose clock signal generation in embedded systems
• Timing reference sources for microcontroller units
• Synchronization circuits in consumer electronics devices

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 rail stability meets the oscillator's operational specifications. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to prevent assembly errors.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. Consider the 3.584 MHz frequency specifically for video-related timing standards or legacy communication interfaces. Evaluate the need for power-down functionality if system battery life optimization is a priority over continuous oscillation.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a manufacturer specializing in quartz crystals and oscillators. The series typically offers various frequency options within a standardized small form factor. The '-PD' suffix indicates the inclusion of power-down capabilities, distinguishing it from standard continuous-operation variants within the same package family.

Oscillators Replacement Considerations

Direct substitutes must match the 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify equivalent frequency accuracy and phase noise specifications. Cross-reference pinout configurations to ensure compatibility without circuit modification.
