3 Description
The TUSB211A-Q1 is a third-generation USB™
2.0 high-speed 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-Q1 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-Q1 includes a preequalization
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-Q1.
The TUSB211A-Q1 improves signal quality without
altering packet timing or adding propagation delay or
latency.
The TUSB211A-Q1 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-Q1 is compatible with USB On-The-
Go (OTG) and Battery Charging (BC) protocols.
