Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency configuration and output enable pin settings against the datasheet before ordering. Confirm that the LVPECL output format matches the receiving device requirements. Ensure the 3.3 V power supply tolerance aligns with the specified 2.97 V to 3.63 V operating range. Check for any required external components such as decoupling capacitors or termination resistors.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when dual-frequency outputs are required from a single package. Consider the LVPECL output format for compatibility with high-speed receivers. Evaluate the 130 mA current consumption against system power budgets. Verify that the 7x5 mm footprint fits the PCB layout constraints compared to other Si552 variants.

Pin ConfigurableSelectable Oscillators Part Context

This part belongs to the Si552 family of programmable VCXOs. It shares the same physical dimensions and general interface characteristics with other models in the series, such as the 552AE and 552AK. The primary distinction lies in the specific frequency values and the dual-frequency feature set defined by the suffix code.

Pin ConfigurableSelectable Oscillators Replacement Considerations
