Oscillators Procurement Notes

Verify the specific frequency suffix matches the required system clock speed before ordering. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD package footprint is compatible with the PCB layout. Check the enable pin configuration requirements against the host controller GPIO capabilities. Review the latest datasheet for any updates on mechanical dimensions or recommended soldering profiles.

Oscillators Selection Notes

Choose this component when a low-voltage 1.8V operation is required for the timing source. Select based on the need for an enable/disable feature to reduce standby power consumption. Consider the ±50ppm stability specification against the system's jitter tolerance requirements. Evaluate the physical size constraints of the 4-SMD package within the available board space. Compare the operating temperature range against the environmental conditions of the final application.
