Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the enable/disable pin logic levels are compatible with your controlling microcontroller or FPGA to prevent unintended oscillator states during operation.

Selection Notes

Select this component when a precise 75.49472 MHz reference is required in a minimal footprint. Consider the 1.8V operating voltage and LVCMOS output characteristics for compatibility with low-voltage digital circuits. Evaluate the need for enable/disable control if power efficiency is a priority in the target application environment.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6 mm package.
