Texas Instruments TUSB8020BPHP REVA User Manual page 3

The Texas Instruments TUSB8020BPHP REVA evaluation module is a functional board design of a single
device that implements both a USB 3.0 hub and a USB 2.0 hub. The EVM can support both SuperSpeed
(SS) and USB 2.0 (HS, FS, and LS) operation on its USB ports. This EVM is intended for use in
evaluating system compatibility, developing optional EEPROM firmware, and validating interoperability.
This EVM also acts as a hardware reference design for any implementation of the TUSB8020B.
Upon request, layout files for the EVM can be provided to illustrate techniques used to route the
differential pairs, use of split power planes, placement of filters and other critical components, and
methods used to achieve length matching of critical signals.
NOTE: The EVM accommodates various lab test components, actual production implementations can be much
smaller.
