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.
The device operates on a single 3.3V supply and
comes in an automotive grade 2 temperature range.
