5.7 kV RMS Digital Isolators for Isolated USB 2.0 High, Full, and Low Speed
► USB 2.0 signaling with automatic detection of low, full, and high speed connections ► 1.5 Mbps, 12 Mbps, and 480 Mbps data rates ► Bidirectional USB isolator for upstream or downstream ports ► Redriving and high speed data retiming for input jitter removal and an open eye ► Flexible clock input options ► 4.5 V to 5.5 V VBUSx or 3 V to 3.6 V operation on each side ► 21 mA typical idle, low or full speed mode supply current ► 48 mA typical idle, high speed mode supply current ► Ultra low power standby in USB 2.0 suspend (L2) or disconnect
Figure 1. ADuM4165 Clock Input from Host Side
► 1.7 mA typical low power standby, upstream supply current ► 20 μA typical low power standby, downstream supply current ► ±8000 V IEC 61000-4-2 ESD protection across the isolation barrier ► Passed CISPR32/EN55032 Class B emissions ► High common-mode transient immunity: 50 kV/μs typical ► Safety and regulatory approvals (pending) ► UL (pending): 5700 V rms for 1 minute per UL 1577 ► CSA Component Acceptance Notice 5A (pending) ► IEC 62368-1, IEC 61010-1 and IEC60601-1 ► VDE certificate of conformity (pending) ► DIN V VDE V 0884-11 (VDE V 0884-11):2017-01
Figure 2. ADuM4166 Clock Input from Peripheral Side
► Operating temperature range: −55°C to +125°C ► 20-lead, wide-body, increased creepage SOIC_IC package with The ADuM4165/ADuM41661 are USB 2.0 port isolators, utilizing 8.3 mm creepage and clearance 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. ► USB peripheral, USB host, and USB hub isolation ► Electronic test and measurement equipment High speed data is retimed for jitter reduction, requiring an external clock signal or crystal input. The ADuM4165 supports the clock or ► Medical devices and integrated PCs crystal input on the upstream side, and the ADuM4166 supports the ► Industrial PCs and isolated USB ports for debug or upgrade clock or crystal input on the downstream side, offering two options ► USB isolator modules and USB cable isolators 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. 1 Protected by U.S. Patents 7,075,329; 8,432,182; 8,525,547; and 8,564,327.
