The PI3USB221EZUAEX is a special purpose analog switch. It comes within the interface family of electronic components, which provides access and transmission paths to the desired sources or destinations. These switches can help manage signals between various devices and switch these inputs in order to select the correct output signals.

The PI3USB221EZUAEX is a four-channel USB type-B differential switch specifically designed for use in USB 3.0 applications. It offers operation up to 5Gbps, providing four differential switch paths to select between two USB type-B connectors with low RDSON, low capacitance and fast switching times. The switch also supports remote wakeup, providing an easy solution for applications requiring multiple receivers.

The PI3USB221EZUAEX provides four auto-directional (bidirectional) channels for signal routing between USB type-B connectors. Each port has an independent Enable signal allowing master devices to set both directions without response time overhead. Routing is done according to the connected devices with the Enable signals being low or high. On the input side, USB data is identified and routed through one of the four data pairs. Output is done in a similar fashion, with the ‘Enable’ signal used to route the data to the correct destination.

The PI3USB221EZUAEX supports the following applications: USB type-C adapters, USB Type B redundant connections, and USB A/B switching. The switch is also applicable to any application requiring an auto-directional signal switch with low On Resistance (Rdson) for signal integrity.

The working principle of the PI3USB221EZUAEX is based on two switching components: an internal switch and a signal routing block. The internal switch consists of two differential pairs connected between two high speed USB type-B connectors on each end. An Enable logic input from the host system is used to control the data routing direction. The routing block consists of dual multiplexers that read the Enable signal and routes the data to the connected USB ports.

The PI3USB221EZUAEX is an effective and efficient switch for applications requiring communication between USB type-B devices. It supports up to 5Gbps throughput, provides four differential channels, and features low on resistance and fast switching times. The support for remote wakeup also makes the switch ideal for applications which have multiple receivers.
