Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD footprint matches the PCB layout dimensions. Cross-reference the part number suffix with manufacturer documentation to confirm availability and manufacturing specifications.

Oscillators Selection Notes

Select this component when a 40.572 MHz timing source is required with low voltage operation. Consider the LVCMOS output level compatibility with downstream logic families. Evaluate the thermal performance and operating temperature range relative to the intended environment. Compare package dimensions against available board space constraints.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on quartz-based timing solutions. The series typically offers standard frequencies with LVCMOS outputs.
