3 Description

The TUSB1021-Q1 is a linear redriver with 1:2

DeMUX or 2:1 MUX function for USB Type-C®

applications. The TUSB1021-Q1 is intended to reside

between a Host and a USB-C® receptacle or between

a USB device and a USB-C® receptacle. The

TUSB1021-Q1 supports USB 3.2 data rates up to

10Gbps and supports USB 3.2 low power states

(Disconnect, U1, U2, and U3)

The TUSB1021-Q1 provides sixteen levels of receive

linear equalization to compensate for inter symbol

interference (ISI) due to cable and board trace loss.

The device operates on a single 3.3V supply and

comes in an automotive grade 2 temperature range.
