Zusammenfassung:A method of operating an embedded universal serial bus (eUSB) repeater includes holding an eUSB receiver and a USB transmitter in active states and holding a USB receiver and an eUSB transmitter in standby states. The method includes receiving by the eUSB receiver a token packet indicative of transmission of a first downstream packet, and transitioning the USB receiver and the eUSB transmitter from the standby states to the active states responsive to the token packet. The method includes transmitting the token packet by the USB transmitter. The method includes receiving by the eUSB receiver a downstream packet or receiving by the USB receiver an upstream packet within a first timeout period after receiving the token packet, and transmitting the downstream packet by the USB transmitter or transmitting the upstream packet by the eUSB transmitter.
