Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific output configuration and frequency parameters against your system requirements before ordering. Confirm that the 3.3 V supply rail aligns with the specified operating voltage range. Ensure the PCB layout accommodates the 7 mm x 5 mm footprint and 1.65 mm height constraints. Check availability status as this part may have restricted supply conditions.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this model when LVDS outputs are required for noise immunity in high-speed environments. Consider the 15 pF load capacitance for proper circuit matching. Evaluate the 108 mA current consumption against power budget constraints. Compare against other Si552 variants if different output formats like CMOS or LVPECL are needed.

Pin ConfigurableSelectable Oscillators Part Context

This VCXO belongs to the Si552 family, which offers various output formats and frequency ranges. The 552BE000455DG specifically targets applications needing LVDS outputs and dual-frequency capabilities.
