ADUM4165BRIZ

Overview

The ADUM4165BRIZ is a USB 2.0 port isolator utilizing iCoupler technology to support low-speed (1.5 Mbps), full-speed (12 Mbps), and high-speed (480 Mbps) data rates. It features 5700 Vrms isolation, a 20-SOIC package with an 8.3 mm creepage distance, and bidirectional signal transmission. The device operates on 3V to 3.6V or 4.5V to 5.5V supplies, includes upstream clock input for jitter reduction, and supports ultra-low power standby modes.

Feature Summary

• Supports automatic detection of USB 2.0 speeds including low, full, and high speed
• Integrates digital isolator channels, USB transceivers, and control logic in one package
• Provides upstream clock input capability for high-speed data retiming and jitter elimination
• Features enhanced EMC robustness and high common-mode transient immunity

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 BRIZ against official Analog Devices documentation to confirm package type and tape/reel configuration. Ensure the component meets required safety certifications such as UL 1577 and IEC standards for your application environment. Cross-reference the datasheet revision date to confirm current parameter validity before integration.

Selection Notes

Select this component when upstream clock input is required for high-speed USB 2.0 applications to minimize jitter. Compare with the ADuM4166 if downstream clock input is preferred instead. Consider the 20-pin wide SOIC package dimensions and the 8.3 mm creepage distance requirements for your PCB layout and isolation barrier design.

Part Context

This part belongs to the ADuM416x series of USB 2.0 port isolators from Analog Devices. These devices simplify system design by combining isolation and USB functionality into a single chip. The series supports dynamic speed selection and offers robust performance for demanding industrial and medical environments requiring high isolation voltages.

Replacement Considerations

The ADuM4166BRIZ serves as a functional substitute within the same family, differing primarily in clock input location (downstream versus upstream). Verify pin compatibility and clock routing requirements before substitution.
