Specialized Procurement Notes

Verify the specific suffix DABI against official Renesas documentation to confirm exact packaging and temperature grade variations. Confirm current lifecycle status as distribution channels may list obsolete or end-of-life inventory. Ensure compatibility with existing PCB footprints matching the 100-FPBGA(9x9) specification before procurement.

Specialized Selection Notes

Select this component when designing systems requiring active signal regeneration for PCIe Gen 3.0 links. Verify that the system design accommodates the thermal requirements of the LFBGA package. Ensure the host controller supports I2C configuration if dynamic register adjustments are required during operation.

Specialized Part Context

This part is a member of the Renesas 89HT0808P family of PCIe retimers. The family includes variants such as the 89HT0808PYBABGI and evaluation tools like the 89KTT0808P. These components share common architectural features for handling high-speed serial data transmission across complex motherboard layouts.

Specialized Replacement Considerations

Direct substitutes within the same pin-compatible family include the 89HT0808PYBABGI. Verify functional equivalence regarding supported PCIe generations and lane counts. Consult Renesas obsolescence notices to ensure long-term availability for production runs.
