Key Features
- USB 3.1 Gen 2 operation at up to 1250 Mbps per port enables 10 Gbps SuperSpeed USB hub expansion with full backward compatibility
- Integrated I2C, SPI, I2S, and SMBUS interfaces allow configuration and audio data routing alongside USB hub functionality
- 100-pin VQFN package with exposed thermal slug provides a compact 12mm x 12mm footprint for high-port-count hub designs
- SMBUS-controlled per-port power management enables individual port enable/disable and over-current protection from a system host
- FlexConnect USB port assignment supports downstream port remapping for dock and hub designs without PCB redesign
Applications
The USB7206T/KDX suits USB 3.1 Gen 2 dock stations, embedded computing modules, and industrial panel PCs requiring 6 downstream USB ports from a single upstream connection at 1250 Mbps. It is used in laptop docking stations to simultaneously drive displays via USB-C Alt Mode, charge devices at 100W, and stream I2S audio data to speakers. The VQFN-100 package and integrated SMBUS control make it a fit for space-constrained server blades and medical instrument USB expansion hubs.

Frequently Asked Questions
What is the maximum data transfer rate of the USB7206T/KDX and how many downstream ports does it support?
The USB7206T/KDX supports USB 3.1 Gen 2 at 1250 Mbps (10 Gbps raw line rate) and provides 6 downstream ports. Each port independently negotiates speed from USB 2.0 480 Mbps to USB 3.1 Gen 2 10 Gbps, allowing mixed-speed device connections. The 25 MHz internal clock drives the hub controller logic, while the USB 3.1 PHY handles high-speed serialization.
How does the USB7206T/KDX integrate SMBUS control for per-port power management in a dock station design?
The USB7206T/KDX exposes a SMBUS slave interface that allows the host system to read per-port current consumption in milliamps, enable or disable individual downstream ports, and configure over-current thresholds in 100 mA steps from 100 mA to 3 A. This lets firmware implement intelligent power allocation across 6 ports from a shared 5V rail without additional power management ICs.
Can the USB7206T/KDX be used in an industrial embedded PC requiring USB 3.1 hub expansion on a space-constrained motherboard?
Yes. The USB7206T/KDX is packaged in a 100-pin VQFN measuring 12mm x 12mm with 0.5 mm pitch, making it suitable for 4-layer PCB designs. The hub requires no external oscillator since it operates from a 25 MHz internal clock, and I2C or SPI configuration at boot eliminates the need for an external EEPROM in static configurations, reducing BOM and total PCB area by approximately 30% versus discrete hub solutions.
How does USB7206T/KDX handle audio routing compared to a hub controller without I2S support?
Unlike standard USB hub controllers, the USB7206T/KDX integrates an I2S audio interface that routes USB Audio Class 2.0 streams from the upstream USB port to an I2S speaker or codec at sample rates up to 192 kHz and 24-bit depth, without CPU involvement. This allows dock stations to deliver bit-perfect audio to 192 kHz DACs while simultaneously transferring data at 1250 Mbps on other ports.
