HOW DOES IT WORK?
USB MUX Click is based on the TS3USB30E, a USB 2.0 1:2 multiplexer/demultiplexer switch with a single enable from Texas Instruments. It is an ESD-protected device capable of bidirectional switching of high-speed USB 2.0 signals while offering little or no attenuation of the high-speed signals at the outputs. Besides the ESD protection, the TS3USB30E offers a low bit-to-bit skew and high channel-to-channel noise isolation. Also, besides USB 2.0, it is compatible with USB 1.1 standard. The maximum speed the TS3USB30E is capable of is 480Mbps at USB 2.0.
USB MUX Click communicates with the host MCU using a few GPIOs. The OE bus-switch enable pin allows users to isolate the bus when not in use and consume less current. With a LOW logic level set on the OE pin, you can use it in combination with the SEL pin to select one of two USB signal paths and connect it to a common USB signal path, with a LOW logic level to a USB1 and a HIGH logic level to a USB2. The USB1 is set by default over the pull-down resistors R5 and R6, which puts both OE and SEL lines in a low logic state. In addition, the VBUS LED will indicate if the powered USB device is connected to the USB MUX Click.
This Click board™ can only be operated with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development
