Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific part number suffix against official Skyworks documentation to confirm the exact output format and frequency configuration. Ensure that the ordering suffix matches the required LVPECL interface and dual-frequency specifications. Cross-reference the manufacturer's latest datasheet to validate electrical parameters and mechanical dimensions before procurement to avoid compatibility issues with existing circuit designs.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this model when a dual-frequency VCXO with LVPECL outputs is required for high-performance timing applications. Consider the 10 MHz to 1.4 GHz operational range and the 130 mA current consumption during power budgeting. Verify that the 7 mm x 5 mm SMD footprint fits the available PCB space. Confirm that the -40°C to +85°C industrial temperature range meets the environmental requirements of the target application.

Pin ConfigurableSelectable Oscillators Part Context

This component is part of the Si552 family of pin-configurable oscillators from Skyworks Solutions. The family provides various output formats and frequency options within a standardized 6-SMD package. The 552AD variant specifically denotes the LVPECL output configuration. This series is designed to replace multiple discrete oscillator solutions by offering configurable frequencies and interfaces in a single form factor.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Direct substitutes include other Si552 series variants with matching LVPECL outputs and similar frequency ranges, such as the 552AC or 552AJ series parts. Verify that any replacement maintains the same 7x5mm package dimensions and 3.3V supply requirements. Check if the alternative part supports the required dual-frequency operation and current consumption limits.
