PRODUCT OVERVIEW

What Is the ISOUSB211DPR?

ISOUSB211DPR is a galvanically-isolated USB 2.0 compliant repeater from Texas Instruments supporting low speed (1.5 Mbps), full speed (12 Mbps), and high speed (480 Mbps) signaling rates.[reference:0][reference:1] 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.[reference:2]

The ISOUSB211DPR also supports automatic role reversal - if after disconnect a new connect is detected on the Upstream facing port, 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.[reference:3] The device has inbuilt programmable equalization to cancel signal loss caused by board traces, helping meet USB2.0 high-speed TX and RX eye-diagram templates.[reference:4]

Using a silicon dioxide (SiO₂) insulation barrier with a withstand voltage of up to 5700 VRMS and a working voltage of 1500 VRMS, the device protects against high voltage and prevents noise currents from the bus from entering the local ground.[reference:5] The ISOUSB211DPR is available for reinforced isolation and supports a wide ambient temperature range of –40°C to 125°C.[reference:6]

USB 2.0 Compliant Supports Low Speed (1.5 Mbps), Full Speed (12 Mbps), and High Speed (480 Mbps) signaling.[reference:7]

Reinforced Isolation 5700 VRMS withstand voltage, 1500 VRMS working voltage, 8000 VPK VIOTM per VDE 0884-17.[reference:8][reference:9]

Automatic Role Reversal Supports USB OTG and Type-C DRP designs with automatic Upstream/Downstream port reversal.[reference:10][reference:11]

Circuit Considerations for ISOUSB211DPR

Power Supply Configuration

The ISOUSB211DPR offers flexible power supply options for each side:

VBUSx Mode: Connect a 4.25 V to 5.5 V supply to VBUSx. Internal LDO generates V3P3Vx.[reference:42]
External 3.3 V Mode: Connect VBUSx and V3P3Vx to an external 3.3 V supply.[reference:43]
External 1.8 V Mode: Connect VCCx and V1P8Vx to an external 1.8 V supply.[reference:44]
V1OK and V2OK pins indicate power-up status of each side.[reference:45]

Equalization & CDP Configuration

Programmable equalization settings compensate board trace loss:

EQ1x (Side 1): EQ10 (LSB) and EQ11 (MSB) set equalization for Upstream port.[reference:46]
EQ2x (Side 2): EQ20 (LSB) and EQ21 (MSB) set equalization for Downstream port.[reference:47]
CDPENZx: Active low signals enable CDP advertising on corresponding port.[reference:48][reference:49]
Refer to the datasheet for equalization code settings based on board trace loss.
