ADuM4165 & ADuM4166 USB 2.0 Port Isolators

Analog Devices Inc. ADuM4165 and ADuM4166 USB 2.0 Port Isolators utilize iCoupler® technology to dynamically support all USB 2.0 data rates, low (1.5 Mbps), full (12 Mbps), or high (480 Mbps), as required. The ADUM4165 and ADUM4166 support host isolation with automatic speed negotiation as well as peripheral isolation. High-speed data is retimed for jitter reduction, requiring an external clock signal or crystal input. The ADuM4165 supports the clock or crystal input on the upstream side, and the ADuM4166 supports the clock or crystal input on the downstream side, offering two options to best suit the system design. Analog Devices Inc. ADuM4165 and ADuM4166 USB 2.0 Port Isolators are housed in a SOIC-20 wide-body package and feature a -55°C to +125°C operating temperature range.
