Procurement Notes

Verify the manufacturer origin carefully, as similar part numbers are listed under Intel or Lantiq in public databases. Confirm the specific revision suffix matches the required hardware version. Ensure the package type corresponds to the 80-pin QFP specification. Check for lead-free compliance status if required by local regulations. Validate the component against official datasheets before integration into production designs.

Selection Notes

Select this component based on its specific ISDN controller capabilities and 3.3V operation. Compare pin compatibility with existing PCB layouts due to the 80-pin QFP footprint. Consider the commercial temperature range limits for environmental suitability. Verify that the CMOS technology meets the power consumption requirements of the target application. Ensure availability from authorized sources given the age of the product family.

Part Context

This component belongs to the PSB series of telecom integrated circuits produced by Lantiq. Similar parts in this lineage include the PSB21553 and PSB2168, which share the same 80-pin QFP packaging and ISDN controller classification. These devices represent legacy solutions for digital telephony interfaces, often superseded by newer broadband technologies but still relevant for specific legacy system maintenance.

Replacement Considerations

Publicly available substitute part numbers for the PSB8301VV1.1 were not identified in the provided reference data. Cross-referencing with the PSB21553 or PSB2168 may be necessary for functional equivalents, though specific electrical parameter matching is required.
