Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6 mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 20.4608 MHz reference is required for LVCMOS-compatible digital interfaces. Consider the 1.8V operating voltage constraint and the availability of a power-down pin if low-power standby modes are necessary for the application. Evaluate the small form factor suitability for dense board layouts compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and voltage options within a standardized 4-SMD footprint.
