Oscillators Procurement Notes

Verify the specific suffix 'TNF' against the manufacturer's latest datasheet to confirm pinout orientation and tape-and-reel specifications. Ensure the ordering part number matches the required frequency tolerance and load capacitance. Cross-reference with authorized distributors to confirm availability status, as some listings may indicate discontinued or obsolete status. Confirm that the 3.3V supply requirement aligns with the target system's voltage rails before procurement.

Oscillators Selection Notes

Select this component when a precise 45.1584 MHz clock source is required for CMOS-based digital circuits. The ±20 ppm stability is suitable for general-purpose timing applications where high-precision frequency synthesis is not critical. Consider the 3.3V operating voltage and 30 mA current draw to ensure adequate power budget allocation. The enable pin allows for system-level power optimization during idle states. Evaluate the 7.0x5.0mm footprint against available board space constraints.
