USB3.0 HUB adopting extremely high frequency microwave isolation

Abstract

A USB3.0 HUB that uses extremely high frequency microwaves for isolation, including a USB3.0 microwave transmitter and a USB3.0 microwave receiver, using an extremely high frequency EHF (Extremely High Frequency) with a frequency range of 60GHz, both The microwave communication between the communication can be automatically negotiated through the custom communication rules. The USB3.0 HUB at the USB3.0 microwave receiving end can connect four super high-speed USB3.0 terminal peripherals at the same time; during the USB3.0 microwave communication process, The microwave transmission device will not add any additional data in the data stream, so the USB3.0 signal is transparent during the transmission process using the microwave transmission device, and all super high-speed USB3.0 terminal peripherals that comply with the USB3.0 standard can work normally connect.

Description

technical field [0001] The present invention relates to the field of USB3.0 communication, in particular to the technical field of isolated communication between various USB3.0 terminal devices and computers, and specifically refers to a USB3.0 HUB using extremely high-frequency microwave isolation.

Problems solved by technology

[0006] For example, Chinese patent application number 201410572419.4 provides a full-speed USB3.0 interface isolation protection device. Compared with photoelectric isolation, the transformer isolation of this device has a transmission speed of 5Gbps, but due to the use of inductive components, there is a problem of voltage mutual inductance coupling. risk, and cannot fully realize the safety isolation required by the medical field

[0007] In the medical field, due to safety considerations, 4000V electrical isolation between the measuring device and the computer is required. In the past, USB2.0 and USB3.0 can use some transformers for coupling isolation, but as the transmission rate increases to 5Gbps~10Gbps, The traditional transformer coupling isolation scheme can no longer adapt to the transmission of 5Gbps~10Gbps, and the transformer coupling still has some defects in the electrical isolation. The electrical isolation is not as good as the photoelectric coupling method and the microwave coupling method. The photoelectric coupling method and the microwave coupling method Can achieve complete electrical isolation, but the photoelectric coupling method is slow, generally only at 12Mbps
