3 Description
The TUSB211A is a third-generation USB 2.0 highspeed
signal conditioner designed to compensate
both AC loss (due to capacitive load) and DC loss
(due to resistive loss) in the transmission channel.
The TUSB211A leverages a patented design to
speed-up transition edges of USB 2.0 high-speed
signal with an edge booster and increases static
levels with a DC boost function.
In addition, the TUSB211A includes a pre-equalization
function to compensate the inter-symbol interference
(ISI) jitter in application with longer cable length. USB
low-speed and full-speed signal characteristics are
unaffected by the TUSB211A.
The TUSB211A improves signal quality without
altering packet timing or adding propagation delay or
latency.
The TUSB211A helps a system to pass the USB 2.0
high-speed near end eye compliance with a cable as
long as 5 meters.
The TUSB211A is compatible with USB On-The-Go
(OTG) and Battery Charging (BC) protocols.
