18QHTF21-2.133333-OE

Oscillators Overview

The 18QHTF21-2.133333-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 2.133333 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with a maximum seated height of 0.031 inches (0.80 mm). The component supports an operating temperature range from -40°C to 85°C and maintains a frequency stability of ±50ppm.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Compact surface-mount package design

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for low-frequency digital systems
• Embedded system clock sources

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 PCB footprint matches the 4-SMD No Lead package dimensions to prevent assembly issues. Check the operating temperature range suitability for the intended environment.

Oscillators Selection Notes

Select this component when a precise 2.133333 MHz clock source is required with LVCMOS compatibility. Consider the ±50ppm stability requirement for timing-sensitive applications. Evaluate the 1.8V supply constraint against available power domains. The enable/disable feature offers power management flexibility compared to always-on oscillators.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series typically includes various frequencies and voltage options. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations, though verification is needed. This model represents a low-frequency option within the portfolio.

Oscillators Replacement Considerations

Direct replacements must match the 2.133333 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and electrical characteristics such as current consumption and stability. Cross-reference with other manufacturers offering similar low-frequency XO components.
