Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics to guarantee compatibility with your target application environment.

Selection Notes

Select this component when a precise 75.75 MHz clock source is required with low voltage operation. Consider the enable pin feature if power efficiency during idle states is critical. Evaluate the small form factor suitability for dense PCB designs. Compare performance metrics such as phase noise and stability against alternative oscillators to ensure it meets the specific timing integrity needs of the electronic system.

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 4-SMD package. These components are designed for applications requiring reliable clock signals in consumer electronics and industrial equipment. The 'OE' suffix typically denotes specific packaging or tape-and-reel options provided by the manufacturer.

Replacement Considerations

Direct substitutes must match the 75.75 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify equivalent electrical parameters such as frequency stability and phase noise. Check for compatible enable/disable functionality. Consult the manufacturer's cross-reference list for officially approved replacements to ensure functional parity.
