3 Description

ISOUSB211-Q1 is a galvanically-isolated USB 2.0

compliant repeater supporting low speed (1.5 Mbps),

full speed (12 Mbps) and high speed (480 Mbps)

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-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

5000 VRMS and a working voltage of 1500 VRMS. 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. It 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.
