18QHTF21-2.300-OE

Oscillators Overview

The 18QHTF21-2.300-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 2.3 MHz and utilizes LVCMOS output logic levels. The device features an active enable/disable control function, allowing for power management in embedded systems. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component supports a supply voltage of 1.8V, making it suitable for low-voltage digital applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for direct digital logic compatibility
• Active high/low enable/disable pin for power optimization
• Compact surface-mount footprint for space-constrained designs

Oscillators Applications

• Low-power portable electronic devices
• Digital signal processing clock sources
• Microcontroller system timing references

Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's current datasheet to confirm the enable/disable functionality and voltage tolerance. Ensure the 4-SMD no-lead package dimensions match the PCB land pattern requirements. Cross-reference the 2.3 MHz frequency specification with the target circuit's input clock requirements to avoid timing mismatches.

Oscillators Selection Notes

Select this component when a low-frequency, low-voltage clock source with power control is required. The 1.8V operation limits suitability for 3.3V-only systems without level shifting. The small 2.0x1.6mm package necessitates careful placement considerations during assembly compared to larger oscillator packages.

Oscillators Part Context

Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in frequency control products, including quartz crystals and oscillators. The company has decades of experience in the timing industry, producing components for various consumer and industrial electronics markets globally.

Oscillators Replacement Considerations

Compatible replacements within the same series include models such as 18QHTF21-6.300-OE or 18QHTF21-8.300-OE, provided the application can accommodate different operating frequencies. Substitution requires verifying that the new part maintains the same LVCMOS output type, 1.8V supply requirement, and 4-SMD package outline.
