ADUM3165BRSZ-RL

Overview

The ADUM3165BRSZ-RL is a digital isolator utilizing iCoupler technology, designed for USB and RS232 interfaces. It features one channel with bidirectional data transmission capability. The device supports data rates up to 480Mbps and provides an isolation voltage of 3750Vrms. It operates within a supply voltage range of 3V to 3.6V or 3V to 5.5V. The component exhibits a common-mode transient immunity of 40kV/µs and propagation delays of 77ns maximum. It functions across an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Supports automatic speed negotiation for USB 2.0 connections including low, full, and high speeds
• Provides re-driving and retiming capabilities to eliminate input jitter and open eye diagrams
• Features flexible clock input options for upstream and downstream port configurations
• Includes ultra-low power standby modes for both upstream and downstream sides

Applications

• USB peripheral isolation
• USB host isolation
• USB hub isolation

Procurement Notes

Verify the specific suffix BRSZ-RL against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure the procurement source provides valid traceability documentation. Confirm that the component meets the required UL and CSA safety approvals if applicable to the end application. Check for any recent product change notices affecting assembly sites or materials.

Selection Notes

Select this component when bidirectional isolation is required for USB 2.0 host or peripheral applications. Consider the 3750Vrms isolation rating for safety compliance. Evaluate the power consumption in active versus standby modes based on system requirements. Verify compatibility with the target PCB footprint, specifically the 20-SSOP package dimensions.

Part Context

This part belongs to the ADuM3165 series of RMS digital isolators by Analog Devices Inc. It is part of the iCoupler family, which uses magnetic coupling technology instead of traditional optocouplers. The series is designed to replace discrete isolation solutions with integrated, compact components suitable for high-speed data transmission.
