18QHTF21-4.754-OE

Oscillators Overview

The 18QHTF21-4.754-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 4.754 MHz and utilizes LVCMOS output logic levels. The component requires a 1.8V supply voltage and features an enable/disable control function for power management. It is housed in a compact 4-SMD, no-lead package designed for surface-mount assembly.

Oscillators Feature Summary

• LVCMOS output interface
• 1.8V operating voltage
• Enable/Disable control pin

Oscillators Applications

• General clock signal generation
• Embedded system timing
• Consumer electronics circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The enable/disable feature makes it suitable for applications requiring power conservation or dynamic clock gating. Consider the 4.754 MHz frequency point specifically for timing references that do not require higher frequency ranges or different output logic families like HCSL or LVDS.
