3 Description
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
USB 3.1 GEN1 path.
