SLLSF14B June 2017 – May 2019 TUSB546A-DCI
PRODUCTION DATA.
The TUSB546A-DCI supports USB 3.1 Gen1 datarates up to 5 Gbps. The TUSB546A-DCI supports all the USB defined power states (U0, U1, U2, and U3). Because the TUSB546A-DCI is a linear redriver, it can’t decode USB3.1 physical layer traffic. The TUSB546A-DCI 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 TUSB546A-DCI 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 TUSB546A-DCI 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.
