ISOUSB211-Q1 is a galvanically-isolated USB 2.0 compliant repeater supporting low speed (1.5Mbps), full speed (12Mbps) and high speed (480Mbps) signaling rates. The device supports automatic connect and speed detection, reflection of pullups/pulldowns, and link power management, allowing drop-in USB hub, host, peripheral, and cable isolation. The device also supports automatic role reversal. If, after disconnect, a new connect is detected on the Upstream facing port, then the Upstream and Downstream port definitions are reversed. This feature enables the device to support USB On-The-Go (OTG) and Type-C Dual Role Port (DRP) implementations. The ISOUSB211-Q1 has inbuilt programmable equalization to cancel signal loss caused by board traces, which helps in meeting USB2.0 high-speed TX and RX eye-diagram templates. This device uses a silicon dioxide (SiO2) insulation barrier with a withstand voltage of up to 5700VRMS and a working voltage of 1500VRMS. Used in conjunction with isolated power supplies, the device protects against high voltage and prevents noise currents from the bus from entering the local ground. The ISOUSB211-Q1 device is available for reinforced isolation. The device supports a wide ambient temperature range of –40°C to +125°C. The device is available in the small foot-print SSOP-28 (28-DP) package.
