Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm that the part number corresponds exactly to the required frequency and output configuration. Ensure compatibility with I2C interface requirements on the target system board. Confirm package dimensions match the PCB footprint design specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a fixed frequency near 698.81 MHz with LVPECL outputs is required. Consider the Si571 series capabilities for I2C programmability if future frequency adjustments might be necessary. Evaluate the 7x5 mm package size constraints against available board space. Verify that the 2.97 V to 3.63 V supply range aligns with the system's power delivery network.

Oscillators Part Context

This oscillator belongs to the Si571 family of programmable devices from Skyworks Solutions. These components are designed to replace multiple fixed-frequency crystals and oscillators, offering design flexibility through digital programming. The Si571 series is widely used in high-speed serial communication standards where jitter performance and frequency stability are critical parameters.

Oscillators Replacement Considerations

Direct substitutes include other Skyworks Si571 variants with matching frequencies and output formats. Cross-reference part numbers such as those ending in different frequency codes but sharing the same AHA prefix and DG suffix for equivalent electrical characteristics and pinout compatibility.
