ISOUSB211-Q1  
SLLSFW6 – MARCH 2024  
ISOUSB211-Q1 High/Full/Low Speed Isolated USB Repeater  
1 Features  
3 Description  
•
•
Compliant to USB 2.0  
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.  
Supports low speed (1.5 Mbps), full speed (12  
Mbps) and high speed (480 Mbps) signaling  
Does not need external crystal or clock input  
Automatic speed and connection detection  
Supports L1 (sleep) and L2 (suspend) low-power  
states
