Frequently Asked Questions

What maximum data transfer rate does the USB5816/KD support, and which USB standard does it implement?

The USB5816/KD supports a maximum data transfer rate of 625 MBps, corresponding to the USB 3.1 Gen 1 SuperSpeed standard at 5 Gbps per port. This enables fast file transfers and high-bandwidth peripheral connectivity across all downstream USB ports simultaneously in multi-port hub designs.

Which configuration interfaces does the USB5816/KD provide for embedded system integration?

The USB5816/KD supports I2C, SMBUS, SPI, and UART configuration interfaces, giving embedded system designers flexible options to initialize hub registers, enable port power management, and monitor port status at a maximum clock frequency of 25 MHz without requiring host-side USB drivers for configuration.

How does the VQFN-100 package of the USB5816/KD benefit PCB layout in compact docking station designs?

The VQFN-100 package features a square QFN footprint with 100 pins and a 0.47-inch body size, reducing the area occupied by the USB hub controller compared to larger LQFP or BGA alternatives. This is especially valuable in slim docking stations and embedded single-board computers where PCB real estate is at a premium.

When designing an industrial USB hub with per-port power control, what makes the USB5816/KD a suitable choice over discrete USB hub ICs?

The USB5816/KD integrates multi-protocol management interfaces (I2C, SPI, SMBUS, UART) with up to 625 MBps throughput and a 25 MHz configuration clock in a single VQFN-100 IC, eliminating the need for external microcontrollers or power-management chips in per-port switching designs used in industrial automation and medical equipment.
