18QHTF21-2.200-OE

Oscillators Overview

The 18QHTF21-2.200-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fundamental frequency of 2.200 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

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

Oscillators Applications

• General-purpose timing reference for embedded systems
• Clock source for microcontrollers operating at 1.8V
• Digital communication interfaces requiring stable low-frequency clocks

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 2.200 MHz specification. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the LVCMOS output type is compatible with the receiving logic inputs. Check the 4-SMD package dimensions against the PCB footprint requirements before ordering.

Oscillators Selection Notes

Select this component when a precise 2.200 MHz clock signal is needed for 1.8V logic circuits. The enable/disable feature makes it suitable for battery-powered devices requiring power optimization. Consider the operating temperature range and stability requirements relative to the application environment. Compare package size constraints against alternative oscillator families from the same manufacturer.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series typically offers various frequency options within a standardized 4-SMD form factor. These components are designed for general timing applications where moderate stability and low voltage operation are prioritized over high-performance specifications found in TCXO or VCTCXO lines.

Oscillators Replacement Considerations

Direct substitutes must match the 2.200 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility if replacing with similar packages from other manufacturers. Frequency tolerance and temperature stability should be compared to ensure equivalent performance in the final application.
