3 Description

The TUSB522P is a fourth generation, dual-channel,

single-lane USB 3.1 GEN1 redriver and signal

conditioner supporting 5Gbps. The device offers low

power consumption on a 3.3 V supply with its ultralow-

power architecture. The redriver also supports the

USB 3.1 low power modes, which further reduces idle

power consumption.

The dual-channel capability enables the system

to maintain signal integrity on both transmit and

receive data paths. The receiver equalization has

three gain settings to overcome channel degradation

from insertion loss and inter-symbol interference.

These settings are controlled from the EQ pins.

To compensate for transmission line losses, the

output driver supports configuration of De-Emphasis

with pins DE. Additionally, automatic LFPS De-

Emphasis control allows for full USB 3.1 compliance.

These settings allow optimal performance, increased

signaling distance, and flexibility in placement of the

TUSB522P in the USB 3.1 GEN1 path.
