GENERAL DESCRIPTION

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.
