• LVCMOS output signal compatibility
• Integrated Enable/Disable functionality
• Compact 4-SMD No Lead surface mount package

Oscillators Applications

• General purpose clock generation
• Digital signal processing systems
• Embedded controller timing sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target circuit's power rails. Ensure the 2.0x1.6 mm footprint matches your PCB layout constraints. Check for any specific environmental operating temperature ranges required by your application standards.

Oscillators Selection Notes

Select this component when a precise 18.528 MHz reference is needed in a minimal footprint. The 1.8V operation makes it suitable for low-power portable devices. The Enable/Disable feature allows for dynamic power saving during idle periods. Consider the LVCMOS interface compatibility with downstream logic levels to ensure signal integrity without additional buffering.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6 mm package. The -OE suffix typically denotes specific packaging or tape-and-reel options provided by the manufacturer. These oscillators are designed for high reliability in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical pinout and package dimensions but different frequencies, such as 18QHTF21-21.200-OE or 18QHTF21-10.180-OE, provided the frequency difference is acceptable for the application.
