Eight-channel I²C redriver in a 100-BGA — what the 6.25 Gbps rating means for the bus
The Renesas 89HP0608RZBABGI is an 8-channel I²C buffer and redriver. Each channel supports a maximum data rate of 6.25 Gbps. The 100-LFBGA package (9x9 mm body, 100-ball CABGA) packs eight independent redriver channels into a footprint that fits on a mid-density PCB without dominating board area. Surface-mount assembly is standard; the BGA requires controlled-depth vias and a solid ground plane under the center of the package for thermal and signal-integrity reasons. Typical applications include server motherboards, storage backplanes, network switches, and any multi-point I²C bus that needs signal reshaping over distance. The part is ROHS3 compliant and carries an active lifecycle status — no last-time-buy risk for production programs.
Active lifecycle — no obsolescence concern for the BOM line
The 89HP0608RZBABGI is listed as Active with ROHS3 compliance. For a procurement decision, this means the part can be specified into new designs without planning for a near-term requalification cycle. The independent distribution channel sources it against an RFQ; current availability and pricing are confirmed at quote time.
