Oscillators Procurement Notes

Verify the exact part number against official Skyworks documentation to ensure compatibility with system requirements. Confirm that the CMOS output format and 1.8 V supply voltage align with the target circuit design. Check for any recent product change notices or lifecycle status updates directly from the manufacturer before procurement.

Oscillators Selection Notes

Select this component when a low-voltage 1.8 V supply is required alongside CMOS outputs. Ensure the application can accommodate the I2C programming interface for frequency adjustments. Verify that the 7 mm x 5 mm footprint fits the PCB layout constraints and that the operating temperature range meets environmental specifications.

Oscillators Part Context

This part belongs to the Si570 family of programmable oscillators, known for wide frequency ranges and digital tuning capabilities. It serves as a drop-in replacement for fixed-frequency crystals in designs requiring frequency agility. The series is widely used in telecommunications and computing infrastructure.

Oscillators Replacement Considerations

Direct substitutes include other Si570 variants with matching voltage and output formats, such as 570JCC000121DG, provided the frequency and package dimensions are compatible.
