Description
Technical Field
The invention relates to the field of electronic equipment, in particular to a system for realizing positive and negative insertion of a Type-C interface.
Background
The Type-C is a connecting interface of the USB interface, can be inserted without dividing the front side and the back side, has the size of about 8.3mm multiplied by 2.5mm, and supports the functions of charging, data transmission, display output and the like of the USB standard like other interfaces. Currently, there are two main methods for realizing the forward and reverse insertion functions of the Type-C interface in the industry:
first, referring to fig. 1, the USB SS 2:1Mux implementation is added to the host SOC, but in this implementation, due to the introduction of Mux (multiplexer), the production cost is increased, and the design difficulty is increased.
Secondly, referring to fig. 2, in this scheme, when a triple-play Type-C docking station (USB-A, VGA/HDMI and charger) is connected, there must be a port in the master controller that is directly connected to the DP port of the docking station (for converting to VGA or HDMI), which may cause an error in this port, so that the OS interface periodically sends an error prompt of "unknown USB device" or "USB device cannot identify", which seriously affects the user experience.
In summary, most manufacturers will choose the first method due to the user experience disadvantages of the second method, but as mentioned above, the first method has low design flexibility and inevitably incurs high cost, which results in at least $ 0.5. Therefore, there is a need for improvement in the existing prior art solutions.
