Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 3.3V supply voltage aligns with your system power rails. Ensure the PCB footprint matches the 6-SMD No Lead package dimensions provided in the official datasheet to prevent mounting issues during assembly.

Oscillators Selection Notes

Select this component when a stable 48 MHz reference is needed within a -40°C to +85°C environment. The ±2 ppm stability suits applications demanding moderate precision without the cost of higher-grade oscillators. Consider the CMOS output level if interfacing directly with standard digital inputs without additional buffering.
