Oscillators Procurement Notes

Verify the specific operating temperature grade required for your application, as datasheets indicate variations between -20°C/+70°C and -40°C/+85°C ranges. Confirm that the 2.5V supply voltage aligns with your system's logic levels. Ensure the 4-pin SMD footprint matches your PCB layout constraints before finalizing orders.

Oscillators Selection Notes

Select this model when a precise 4 MHz reference is needed with low jitter characteristics. The HCMOS interface ensures compatibility with standard logic families. Consider the enable pin feature if dynamic power control is necessary. Verify the ±25 ppm stability meets your system's timing tolerance requirements compared to higher precision alternatives.

Oscillators Part Context
