ADUM4165BRIZ-RL

Overview

The ADUM4165BRIZ-RL is a USB 2.0 port isolator utilizing iCoupler technology to support data rates of 1.5 Mbps, 12 Mbps, and 480 Mbps. It features 5700 Vrms isolation voltage and operates within a -55°C to +125°C temperature range. The device uses a 20-SOIC package with an 8.3 mm creepage distance. Supply voltages include 3.0V to 3.6V or 4.5V to 5.5V per side. Typical power consumption is 21 mA in idle/low-speed modes and 48 mA in high-speed mode.

Feature Summary

• Supports automatic speed negotiation for USB 2.0 low, full, and high-speed connections
• Integrates digital isolator channels, USB transceivers, and control logic in a single wide-body SOIC_IC package
• Provides re-driving and high-speed data retiming to eliminate input jitter

Applications

• Isolation of USB host ports
• Isolation of USB peripheral devices
• USB hub isolation
• Electronic test and measurement equipment
• Medical kits and integrated PCs

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm that the component utilizes upstream clock input capabilities as defined by the ADuM4165 variant. Ensure the procurement matches the 20-SOIC physical dimensions and electrical specifications required for the target design.

Selection Notes

Select this component for designs requiring robust USB 2.0 isolation with high common-mode transient immunity. The ADUM4165 variant specifically supports upstream clock inputs, which is necessary for high-speed data retiming applications. Consider the extended industrial temperature range and enhanced EMC performance for demanding environments.

Part Context

This part belongs to the ADUM416x series of USB 2.0 port isolators from Analog Devices. It integrates isolation barriers with USB transceiver functions to simplify system design. The series addresses challenges related to signal integrity and electromagnetic compatibility in isolated USB interfaces.

Replacement Considerations

The ADUM4166BRIZ-RL serves as a functional substitute, differing primarily in downstream clock input support rather than upstream configuration.
