8.3.1 USB 3.1

The TUSB1042I supports USB 3.1 Gen1/Gen2 data rates up to 10 Gbps. The TUSB1042I supports all the USB defined power states (U0, U1, U2, and U3). Because the TUSB1042I is a linear redriver, it can’t decode USB3.1 physical layer traffic. The TUSB1042I monitors the actual physical layer conditions like receiver termination, electrical idle, LFPS, and SuperSpeed signaling rate to determine the USB power state of the USB 3.1 interface.

The TUSB1042I features an intelligent low frequency periodic signaling (LFPS) detector. The LFPS detector automatically senses the low frequency signals and disables receiver equalization functionality. When not receiving LFPS, the TUSB1042I will enable receiver equalization based on the EQ[1:0] and SSEQ[1:0] pins or values programmed into EQ1_SEL, EQ2_SEL, and SSEQ_SEL registers.
