Low-emission isolated USB repeater supporting low, high and full speed

ISOUSB211 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 pull-ups/pull-downs, 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 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 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.
