Abstract: Various configurations of high-speed data communication devices, e.g., repeaters, interfacing between a host and a peripheral, and methods of operating the same, are provided to improve the Remote Wake sequence. Repeaters include circuitry to detect the start of Resume signaling or the end of Resume, following initiation of Remote Wake. In an example, pull-up resistors coupled to upstream differential signal lines and a detection circuit with a current source are controlled to detect the start of Resume signaling. In another example, the upstream-side pull-resistors and an enable signal to an upstream-side transmitter are controlled to detect the end of Resume.

Abstract: A system and method are disclosed for providing electrically isolated communications between two USB2 devices. Two isolating eUSB2 repeaters are utilized to implement a digital isolation barrier between the two USB2 devices. The isolating eUSB2 repeaters are configured to broker isolated communications between the two USB2 devices using a modified eUSB2 protocol that allows the two isolating eUSB2 repeaters to interoperate across the isolating barrier. The modified eUSB2 protocol allows the two isolating eUSB2 repeaters to broker isolating communications on behalf of the USB2 devices without the use of an accurate clock signal. The modified eUSB2 protocol utilized by the isolating eUSB2 repeaters is configured in particular to support certain end-of-packet translations between USB2 data and the modified eUSB2 protocol, management of certain USB2 bus state transitions and assignment of roles to the two isolating eUSB2 repeaters.

Abstract translation: 公开了一种用于在两个USB2设备之间提供电隔离通信的系统和方法。 两个隔离的eUSB2中继器被用来实现两个USB2设备之间的数字隔离屏障。 隔离式eUSB2中继器配置为使用修改的eUSB2协议来代理两个USB2设备之间的隔离通信，允许两个隔离的eUSB2中继器在隔离屏障之间进行互操作。 经修改的eUSB2协议允许两个隔离的eUSB2中继器代替USB2设备进行隔离通信，而无需使用精确的时钟信号。 隔离eUSB2中继器使用的修改后的eUSB2协议特别配置为支持USB2数据和修改的eUSB2协议之间的特定端到端转换，某些USB2总线状态转换的管理以及角色分配给两个隔离eUSB2转发器。
