  • Page 3: Introduction

    Note the EVM dimensions of 3” x 4” accommodates various lab test components, actual production implementations can be much smaller. Also, the TUSB8040AEVM is laid out to accept either a TUSB8040A unit or a socket. This socket functionality would not need to be duplicated on a production implementation.

  • Page 4: Hardware Overview

    3.0 jitter transfer function. USB Port Connectors The TUSB8040AEVM is equipped with 5 standard nine pin USB 3.0 port connectors. One of these five connectors, J1, is a Type B connector designed to interface with an upstream USB host or hub. The remaining connectors, J2-J5, are Type A connectors for connection to downstream devices or hubs.

    5 A because the hub must be able to source significant power on its downstream ports (900 mA per port). The TUSB8040AEVM uses a single channel LDO voltage regulator to drop 5 V to 3.3 V. The TPS7A4533, U20, is a 1.5-A output linear regulator (SLVS720). The 1.1-V core voltage required by the TUSB8040A is sourced by the 3.3-V rail to reduce unnecessary heat dissipation.

  • Page 6: Optional Circuitry

    ESD events are a concern, especially if the end equipment requirements exceed the device specifications (i.e. HBM 2000 kV, CDM 500 V) (SLVSAC2). The switches present on the TUSB8040AEVM are intended for TI lab evaluation only and are not required for production designs.

  • Page 7: Hardware Set Up

    Hardware Set Up Configuration Switches The TI TUSB8040AEVM has two sets of switches to facilitate configuration changes. Changing these switch settings without a complete understanding of the result is not recommended. Configuration inputs are only read by the TUSB8040A during power on reset, changing the switch settings while the EVM is powered on will have no effect.
  • Page 8 Port 3 are reported as removable by default. If the switch is set to the ON position, the terminal is pulled low and the TUSB8040A will report a device connected to Port 3 as non-removable.

  • Page 9: Hardwired Configurations

    Hardwired Configurations PORTINDz - The TUSB8040A has an internal pull up on this terminal, so port indicator LED support is not reported to the USB host by default. Since the TUSB8040AEVM has port indicator LEDs, this terminal has been pulled low.

  • Page 10: Troubleshooting

    If installed, remove the serial EEPROM from the EEPROM socket. The EVM does not require an EEPROM to operate. • In the case where a 12-V power supply has been attached to the EVM, the fault is non-recoverable.
