Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply rail is stable within the datasheet specifications. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent soldering defects. Check for any RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a 35.97966 MHz clock signal is required with LVCMOS compatibility. Consider the 1.8V operating voltage constraint for power budgeting. The small 2.0x1.6mm form factor makes it suitable for space-constrained designs. Evaluate the need for standby functionality to optimize system power efficiency compared to continuous-operation oscillators.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various standard frequencies in a compact SMD package.
