High-speed bidirectional passive switch ideal for USB Type-C applications

The Texas Instruments HD3SS3202 is a high-speed bidirectional passive switch in mux or demux configurations suited for USB Type-C applications that support USB 3.1 Gen 1 and Gen 2 data rates. Based on control pin SEL, the device delivers switching on differential channels between Port B or Port C to Port A. The device is a generic analog differential passive switch. It operates with any high-speed interface application that needs a common mode voltage range of 0V to 2V and demands a differential signalling with differential amplitude at a maximum of 1800mVpp. The device has adaptive tracking that makes certain the channel stays unchanged for the full common mode voltage range. The device enables high-speed switching with minimum attenuation to the signal eye diagram with little-added jitter. It uses < 1.65mW (typical) of power when in operation. It has a shutdown mode that is used by the OEn pin resulting < .02µW (typical).
