Introduction

The Texas Instruments TUSB4020B evaluation module is a functional board design of a single device that

implements a USB 2.0 hub. The EVM can support 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 TUSB4020B.

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.
