ZHCSFC8E August 2016 – January 2023 TUSB1046-DCI
PRODUCTION DATA
The TUSB1046-DCI supports USB 3.1 Gen1/Gen2 datarates up to 10 Gbps. The TUSB1046-DCI supports all the USB defined power states (U0, U1, U2, and U3). Because the TUSB1046-DCI is a linear redriver, it can’t decode USB3.1 physical layer traffic. The TUSB1046-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 TUSB1046-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 TUSB1046-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.
