Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the exact part number suffix against official Skyworks documentation to confirm packaging configuration, as 'DG' typically denotes cut tape while 'DGR' indicates reel packaging. Confirm that the required output frequencies match the specific dual-frequency pair defined for this variant. Ensure supply chain partners provide valid RoHS compliance certificates and MSL level 1 handling information. Cross-reference the manufacturer's latest datasheet to validate pinout compatibility and electrical specifications before finalizing procurement orders.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when dual-frequency generation is required without external switching logic. The LVPECL output format dictates interface compatibility with downstream receivers supporting this specific signaling standard. Consider the 130 mA maximum current draw for power budget calculations. The 7x5 mm package size must fit within the designated PCB footprint constraints. Verify that the operational temperature range of -40°C to +85°C meets the environmental requirements of the target application environment.

Pin ConfigurableSelectable Oscillators Part Context

The 552AK000191DG belongs to the Si552 family of dual-frequency VCXOs developed by Skyworks Solutions. This series leverages advanced DSPLL technology to deliver low jitter performance. The 'AK' prefix generally indicates specific frequency pairs and output formats within the broader product line. These oscillators are engineered for compact designs requiring multiple reference frequencies from a single component, reducing board space and complexity compared to using separate single-frequency oscillators.

Pin ConfigurableSelectable Oscillators Replacement Considerations

The parameter-equivalent replacement part number is 552AK000191DGR. This alternative offers identical electrical characteristics and pinout but differs in shipping packaging configuration. Verify that the functional specifications remain unchanged between the DG and DGR variants before substitution.
