Oscillators Procurement Notes

Verify the specific suffix (OE vs PD) against the manufacturer's official datasheet to confirm exact electrical characteristics and pinout definitions. Ensure the operating voltage and load capacitance requirements match the target circuit design before procurement. Cross-reference the part number with the latest revision history to avoid obsolete specifications.

Oscillators Selection Notes

Select this component when a precise 19.56 MHz clock source is required for LVCMOS-compatible logic families. Consider the 1.8V supply constraint and the need for active enable/disable control. The small form factor makes it appropriate for space-constrained designs requiring reliable timing signals without external buffering components.
