Oscillators Procurement Notes

Verify the specific suffix 'D' corresponds to the required -0.25% down-spread profile and 15.000 MHz frequency. Confirm that the 2.5V supply requirement aligns with the target circuit design. Ensure the 4-pad SMD footprint matches the PCB layout specifications. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Oscillators Selection Notes

Select this component when EMI mitigation is critical for signal integrity in digital circuits. The CMOS output simplifies interfacing with microcontrollers and FPGAs. Consider the enable pin functionality if power conservation during idle states is a system requirement. Verify that the operating temperature range meets the environmental conditions of the intended application environment.

Oscillators Part Context
