ADu M3165 (Clock Input from Host Side) Figure 2. ADu M3166 (Clock Input from Peripheral Side) GENERAL DESCRIPTION The ADu M3165/ADu M31661 are USB 2.0 port isolators, utilizing Analog Devices, Inc., i Coupler® technology to dynamically support all USB 2.0 data rates: low (1.5 Mbps), full (12 Mbps), or high (480 Mbps), as required. The devices 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...
