Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency configuration and pinout compatibility during procurement, as the Si552 series offers various programmable options. Confirm that the LVPECL output requirement matches the receiving circuitry specifications. Ensure the 3.3V supply rail stability meets the 2.97V to 3.63V operational window. Check for RoHS compliance status if required by project standards. Validate the 7x5mm footprint against the PCB design constraints before finalizing orders.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when a wide tuning range up to 1.4 GHz is required alongside precise frequency control. The LVPECL output is suitable for driving high-speed digital inputs directly without additional buffering. Consider the 130 mA current consumption for power budget calculations. The -40°C to +85°C industrial temperature range ensures reliability in demanding environments. Compare against other Si552 variants if different output formats or voltage levels are needed.

Pin ConfigurableSelectable Oscillators Part Context

This VCXO belongs to the Si552 family of pin-configurable oscillators from Skyworks Solutions. These devices are engineered for flexibility, allowing customization of frequencies and outputs through ordering suffixes. The 552AD000111DGR specifically targets applications requiring dual-frequency capability and LVPECL signaling.
