  • DisplayPort 2.1 (UHBR up to 20 Gbit/s) x1, x2, x4
  • Thunderbolt™ 3, 2 (20.625 and 10.3125 Gbit/s)
  • On-chip diagnostics including: EyeScope and BER monitors
  • TWI connects to the PD controller for initialization and control
  • Two package options:
    • KB8001: 4x4 mm FCCSP package for small form factor designs
    • KB8002: 5x5mm FCCSP package designed for manufacture (Compatible with KB8010)

Product Benefits

Solution area

Compact 5x5 mm package with smaller external components enables a total solution <50% PCB area versus competitors, which can be used in smaller form factor designs where PCB area is a premium.

Low BOM Cost

No requirement for serial memory which enables reduced BOM cost.

Flexible Orientation

SerDes architecture and crossbar logic supports both source and sink applications.

Low Active Power

Low active power in USB4 and DP-ALT modes, which saves power when connected to USB4 / DP devices.

Compliance Ready

Low risk compliant ready solution for USB4, USB 3.2 and DisplayPort.

Longer PCB traces

Superior channel performance by dynamically correcting for extreme channel characteristics with no system tuning, enables more flexible PCB designs.
