The ADuM4165/ADuM4166 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 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.

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 20-lead, wide-body, increased creepage SOIC_IC with 8.3 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

Protected by U.S. Patents 7,075,329; 8,432,182; 8,525,547; and 8,564,327. Other patents are pending.

Product Detail

The EVAL-ADuM4165EBZ and the EVAL-ADuM4166EBZ allow quick and easy evaluation of the ADuM4165 and ADuM4166 USB isolators, allowing direct connection to USB hosts and peripherals without the need for additional components. The ADuM4165/ADuM4166 employ Analog Devices, Inc., iCoupler® technology to combine isolator channels, USB transceivers, power and timing circuits, control logic and internal terminations, pull-ups, and pull-downs into a single, 20-lead, wide-body, increased creepage SOIC_IC package.

The evaluation boards have a separate ground and power plane for each side of the isolator. This separation enables the evaluation of the ADuM4165/ADuM4166 with galvanic isolation between both sides of these devices. However, the boards have not been certified for safety when using high voltages, and testing must be carried out by qualified personnel only.

Power can be provided on the upstream side from a connected USB host, while an external power supply is required for the downstream side.

For full details on the ADuM4165/ADuM4166, see the ADuM4165/ADuM4166 data sheet, which must be consulted in conjunction with this user guide when using the EVAL-ADuM4165EBZ or the EVAL-ADuM4166EBZ.
