It supports both USB 3.0 SuperSpeed (5Gbps) and USB 2.0 High-Speed (480Mbps) traffic on all four downstream ports simultaneously. The hub operates as a transaction translator (TT) for USB 2.0: when a Full-Speed (12Mbps) or Low-Speed (1.5Mbps) device is connected to a downstream port, the TT converts the transactions to High-Speed for upstream transmission, preventing slow devices from bottlenecking the bus. The upstream port connects to the host via a USB 3.0 cable (2 SS pairs + 1 USB 2.0 pair). Each downstream port provides independent SS and USB 2.0 connections, allowing mixed-speed devices. The hub includes per-port power switching (via external MOSFETs controlled by PWRCTL pins) and per-port over-current detection (via OCSR pins), enabling USB battery charging specification compliance. The 24MHz crystal provides the reference clock for the internal PLL that generates the 5Gbps serial clock. The device supports individual port power control, port indicator LEDs, and SMBus\/I2C configuration. The GRST pin provides a global reset. The internal 1.1V LDO generates the core voltage from the 3.3V supply, requiring external decoupling. The -IRGCR suffix specifies industrial temperature (-40C to +85C), VQFN-48 tape-and-reel. The hub is used in USB docking stations, monitors with USB ports, and industrial USB expansion.","pin_description":"
