Procurement Notes

Verify the specific ordering suffix matches the required frequency tolerance and temperature range. Confirm that the 2.8V supply voltage aligns with your system's power architecture. Ensure the SMD 3225 footprint is compatible with your PCB design rules. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Validate the clipped sine wave output compatibility with downstream logic levels.

Selection Notes

Select this component when a stable 19.2 MHz reference is critical for system synchronization. Consider the ±2.5 ppm stability requirement against your application's jitter tolerance. Evaluate the 2.8V supply constraint against available power rails. Assess the -30°C to +75°C operating range against environmental conditions. Compare the low current draw against battery life requirements for portable implementations.
