The TUSB521-Q1 and
TUSB1021-Q1 are automotive USB3.1 redrivers capable of
multiplexing USB3 signals at data rates of 5Gbps and 10Gbps in
respect to the devices as the redrivers are listed. In
particular, these devices excel in applications which use a USB
Type-C interface for communicating between host and device. USB
signal amplitudes attenuate through a typical FR4 channel,
placing limitations on system trace length at 5Gbps, 10Gbps, and
even higher data rates. A longer channel with large attenuation
results in signal integrity issues at a USB receiver. The
TUSB521-Q1 and TUSB1021-Q1 are used to eliminate or minimize the
attenuation effects of the channel to produce a compatible eye
at the device receiver. Attenuation is minimized by applying
receiver equalization to compensate for cable and board loss due
to intersymbol interference (ISI) and insertion loss. The
TUSB521-Q1 and TUSB1021-Q1 are configurable with 16 receiver
equalization settings for USB signals.
