3 Description

The TUSB521-Q1 is a linear redriver with 1:2 DeMUX

or 2:1 MUX function for USB Type-C? applications.

The TUSB521-Q1 is intended to reside between a

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

device and a USB-C? receptacle. The TUSB521-

Q1 supports USB 3.2 data rates up to 5Gbps and

supports USB 3.2 low power states (Disconnect, U1,

U2, and U3)

The TUSB521-Q1 provides sixteen levels of receive

linear equalization to compensate for inter symbol

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

Operates on a single 3.3V supply and comes in an

automotive grade 2 temperature range.
