18QHTF21-4.655-OE

Oscillators Overview

The 18QHTF21-4.655-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 4.655 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• LVCMOS output interface
• Enable/Disable control pin
• Compact 4-SMD No Lead package

Oscillators Applications

• General purpose timing circuits
• Embedded systems clock sources
• Consumer electronics devices

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 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, small-footprint oscillator is required for applications needing precise 4.655 MHz timing. Consider the enable/disable feature if power conservation is critical. Compare alternative frequencies from the same series if the exact 4.655 MHz rate does not match your system needs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various standard frequencies with consistent LVCMOS outputs and enable functions. The 'OE' suffix typically denotes specific packaging or ordering options within the manufacturer's catalog.

Oscillators Replacement Considerations

Check equivalent models like 18QHTF21-4.655 without the OE suffix for potential compatibility. Verify pinout and electrical characteristics against other 4.655 MHz LVCMOS oscillators from different manufacturers before substitution.
