18QHTF21-2.250-OE

Oscillators Overview

The 18QHTF21-2.250-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 2.25 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. The unit supports an operating temperature range from -40°C to 85°C.

Oscillators Feature Summary

• Integrates an enable/disable pin for power management control
• Utilizes LVCMOS output logic for digital interface compatibility
• Designed in a small form factor surface-mount package

Oscillators Applications

• General purpose timing clock generation
• Embedded system microcontroller clocks
• Consumer electronics timing references

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 2.25 MHz operation. Confirm the 1.8V supply requirement aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout specifications. Check the operating temperature range suitability for the intended environment.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available. Choose based on the need for a small 2.0x1.6 mm footprint. Consider the enable/disable feature if power saving is required. Verify LVCMOS compatibility with downstream logic inputs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies within a consistent 1.8V LVCMOS format. The 'OE' suffix typically indicates the inclusion of an output enable function across the product line.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinout and electrical characteristics but different frequency suffixes, such as 18QHTF21-2.300-OE or 18QHTF21-9.465-OE, provided the frequency difference is acceptable.
