18QHTF21-75.001-PD

Overview

The 18QHTF21-75.001-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 75.001 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a 1.8V supply voltage requirement. A key functional characteristic is the inclusion of a standby or power-down mode capability, allowing for energy conservation 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.

Feature Summary

• Supports LVCMOS output signal compatibility
• Integrates standby and power-down functionality
• Operates on a 1.8V supply voltage

Applications

• Battery-powered electronic devices
• Portable consumer electronics
• General-purpose digital clock generation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V operating voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package dimensions fit within your PCB footprint constraints. Cross-reference the datasheet for precise electrical characteristics to guarantee reliable operation in your intended application environment.

Selection Notes

Select this model when a low-voltage 1.8V oscillator is required for space-constrained designs. The standby feature makes it suitable for applications requiring power management. Ensure the LVCMOS output level matches the input requirements of the downstream logic components. Consider the 75.001 MHz frequency specifically if that exact timing reference is necessary for the system synchronization.

Part Context

This part belongs to the Mercury Electronics XO series, which focuses on quartz-based frequency control solutions. Mercury Electronic has a long history in manufacturing quartz crystals and oscillators, positioning itself as a pioneer in the Taiwan frequency control industry.
