USB Type-C SuperSpeed Active Switch

Powered from a 1.8 V supply, PTN36043 is a very small, low power 2 differential channel 2 to 1 active multiplex/demultiplexer switch. It has an integrated SuperSpeed USB3.1 Gen 1 (also known as USB3.0) redriver IC that can switch two differential signals to one of two locations. The active switch has optimized performance with minimized crosstalk, as required by the high-speed serial interface for type C connector.

PTN36043 has built-in advanced power management capability that enables significant power savings under various different USB3.1 Gen 1 Low-power modes (U2/U3). It can detect link electrical conditions and can dynamically activate/deactivate internal circuitry and logic. The device performs these actions without host software intervention and conserves power.
