18QHTF21-4.636-OE

Oscillators Overview

The 18QHTF21-4.636-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 4.636 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable functionality for power management
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• General clock signal generation for embedded systems
• Timing reference for low-frequency digital circuits
• Consumer electronics requiring stable 1.8V operation

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the enable/disable pin configuration matches the host controller's GPIO capabilities to manage power states effectively during operation.

Oscillators Selection Notes

Select this component when a low-frequency, 1.8V LVCMOS oscillator is required. The enable/disable feature supports power-sensitive designs. Compare against other frequencies in the 18QHTF21 series if different clock speeds are needed. Ensure the small form factor fits within the available PCB space constraints for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronic. The series offers various frequencies including 6.3 MHz and 100.64 MHz variants. All members share similar packaging and electrical characteristics, differing primarily in operating frequency and specific ordering suffixes.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with matching frequencies or compatible LVCMOS outputs from Mercury Electronic. Cross-referencing with identical specifications from other manufacturers requires careful verification of pinout and voltage levels.
