The TUSB522P is a fourth generation, dual-channel, single-lane USB 3.1 GEN1 redriver and
signal conditioner supporting 5 Gbps. The device offers low power consumption on a 3.3 V supply
with its ultra-low-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
