Frequently Asked Questions
What USB data transfer speed does USB7051T-I/KDX support per downstream port and in aggregate?
USB7051T-I/KDX supports USB 3.1 Gen1 at 5 Gbps per port, with an aggregate internal bus bandwidth of 625 MBps. This enables 4 downstream devices to transfer data simultaneously without significant throughput degradation, making it suitable for industrial test equipment, multi-drive storage enclosures, and embedded computing hubs requiring high-bandwidth multi-port USB expansion.
Does USB7051T-I/KDX support USB Power Delivery and which ports can negotiate charging power?
Yes, USB7051T-I/KDX includes a native USB Power Delivery Type-C upstream port capable of negotiating up to 100 W power contracts. The downstream ports include at least 1 PD-capable Type-C port, enabling pass-through charging and alt-mode video for connected devices. This combination suits single-cable docking station designs that deliver 5 Gbps data and high-wattage charging to laptops and tablets via a single USB-C cable.
Which configuration interfaces does USB7051T-I/KDX support for runtime setup in embedded systems?
USB7051T-I/KDX supports I2C and SPI serial interfaces for runtime configuration, allowing host processors to adjust hub parameters such as VID/PID strings, port power management, and downstream port enable/disable. This programmability is critical in embedded industrial panels and OEM computing modules where custom device identification strings and per-port power budgets must be set during factory programming or firmware initialization.
For an in-vehicle infotainment USB hub design, what temperature range does USB7051T-I/KDX cover?
USB7051T-I/KDX is rated for industrial temperature operation from -40°C to +85°C, covering automotive cabin environments, industrial HMI enclosures, and outdoor kiosk installations. The QFN-100 package with exposed thermal pad provides efficient heat dissipation for continuous USB 3.1 Gen1 operation in environments with ambient temperature swings typical of vehicle interiors and factory floors.
