Product Details
The ADuM3165/ADuM31661 are USB 2.0 port isolators, utilizing Analog Devices, Inc., 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 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 input. The ADuM3165 supports the clock or crystal input on the upstream side, and the ADuM3166 supports the clock or crystal input on the downstream side, offering two options to best suit the system design.
The low power standby mode for downstream (Side 2) supports applications with limited available power, such as battery-operated peripherals. The upstream (Side 1) standby current meets USB 2.0 requirements for suspended operation.
The isolators are specified over an extended industrial temperature range of −55°C to +125°C and are available in a compact 20-lead shrink small outline package (SSOP) with 5.3 mm creepage and clearance.
APPLICATIONS
- USB peripheral, USB host, and USB hub isolation
- Electronic test and measurement equipment
- Medical devices and integrated PCs
- Industrial PCs and isolated USB ports for debug or upgrade
- USB isolator modules and USB cable isolators
