18QHTF21-17.280-OE

Oscillators Overview

The 18QHTF21-17.280-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 17.28 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated enable/disable pin for power control
• Compact 4-SMD surface-mount package design

Oscillators Applications

• Digital signal processing circuits
• Communication equipment timing references
• Embedded system clock generation

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 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The integrated enable function makes it suitable for battery-powered or power-sensitive designs. Consider the small 2.0x1.6 mm package size for space-constrained layouts where traditional through-hole oscillators cannot fit.
