TUSB6020 EVM
The TUSB6020 is a USB 2.0 high-speed, On-the-Go (OTG) high-performance dual-role USB controllerwith intergrated PHY designed for a seamless connection to the VLYNQ serial interface, and is ideal for awide range of applications. The USB OTG dual-role controller can operate either as a function controllerfor a USB peripheral or as the host/peripheral in point-to-point or multi-point communications with otherfunctions. The integrated USB 2.0 PHY provides one-port operation at low speed (1.5 Mb/s), full speed(12 Mb/s), and high speed (480 Mb/s).
The device is fully compliant with Universal Serial Bus Specification Revision 2.0 and On-The-GoSupplement to the USB 2.0 Specification Revision 1.3.
The TUSB6020 EVM is compatible with several TI DSP platforms that are equipped with a mini-PCIinterface with an active VLYNQ connection. This includes the DM6437 Digital Video DevelopmentPlatform as well as the C6424 DSP Evaluation Module. The TUSB6020 EVM can provide a variety of USBfunctions to a DSP platform. Specifically, the TUSB6020 EVM has proven OTG host and OTG devicecapability. Alternatively, the TUSB6020 EVM can be configured to respond as a USB mass storagedevice.

www.ti.com TUSB6020 EVM Features
•The TUSB6020 EVM is shipped with a USB mini-AB connector, J13, installed. There are alsooverlapping footprints on the EVM for a USB Standard A connector and a USB Standard B connector.If one of these options is needed, the mini-AB connector can be de-soldered from J13, and a Bconnector added to J12 or an A connector added to J11. There is also a jumper, J14, that allows forthe ID pin of the mini-AB connector to be grounded for test purposes if installed.•There are two clock source options available on the TUSB6020 EVM. There is a 24-MHz crystal clocksource, X2, and a 19.2-MHz oscillator clock source, X1. The clock source used by the TUSB6020 isdetemined by the setting of Switch 7 of the toggle switch set, S1.•The toggle switches at S1 connect to the GPIO7:0 pins of the TUSB6020. Switch 8 must be turned onat power-up (GPIO7 = low) for the TUSB6020 to operate properly. The setting of switch 7 at power upis used to determine the clock source. After power up, any of the switches can be used as inputs forthe associated GPIOs.•A reset to the TUSB6020 device can be generated in a variety of ways on the TUSB6020 EVM. Areset can be manually generated using the pushbutton installed at SW1. A reset is generatedautomatically based on the power-good outputs of the voltage regulator at power up. In addition, byinstalling jumper, J9, a reset can be generated and held by installing the jumper to ground.•There are a number of test jumpers and test points on the TUSB6020 EVM that are not necessary toTUSB6020 EVM operation but could be used to test functionalities for use in production designs. Someof these are: the SLEEP jumper at J16, the 1.5V_SWEN jumper at J15, the 3.3V_SWEN jumper atJ10, and the jumper on the level shifted version of CP_EN at J4.•The power circuitry of the TUSB6020 EVM is set up to allow for easy power measurements. The 5-Vpower jack at P1 is not installed because the TUSB6020 can be powered by the DSP platform via themini-PCI interface. To take a power measurement, the trace connecting the associated jumper pinsshould be cut and the jumper installed so that an ammeter can be inserted between the pins. See theschematic for particulars on voltage rails, but traces connect the jumper pins on the following: J37, J38,J39, J40, J42, J43, J45, J46, J51, and J59.
1. Check that switches 7 and 8 in S1 are set to select the TUSB6020 normal device mode and the clocksource. For normal operation, switch 8 must be turned on to pull GPIO7 low. Switch 7 must be turnedon to select the XI clock input (24 MHz) with GPIO6 pulled low or left off to select the CLKIN clockinput (19.2 MHz) with GPIO6 pulled high.2. Insert the TUSB6020 EVM into the mini-PCI slot of the unpowered TMS320C6437 or TMS320C6424EVM.
3. Connect a UART cable from the TMS320C6437 EVM to a PC.4. Connect a mini-USB cable from EMU-USB, J501, of the TMS320C6437 EVM to a PC loaded with theCode Composer, CCStudio v3.3, C6424 software.5. Add wallpower to 5V IN, J14, of the TMS320C6437 EVM.6. Check that LEDs, DS5 and DS502, are lit on the TMS320C6437 EVM.7. Check that LED D1 is lit on the TUSB6020 EVM.
