Equipment
This user’s guide describes the setup and operation of the TUSB3200EVM2
platform. This PCB contains two main active parts: TUSB3200A STC (TI USB
streaming controller) and crystal CS4228 codec. This PCB is referred to as the
TUSB3200EVM2 from this point on. Familiarity with emulator hardware and
software is required and assumed throughout this user’s guide.

1.1 Hardware

TUSB3200EVM2.

USB EVM2
The TUSB3200EVM2 hardware platform measures 6.0′′ X 5.5′′ (W × L).
Throughout this document text inside of parentheses (ex.) represents
reference designators that identify components located on the
TUSB3200EVM2.
The hardware setup for the TUSB3200EVM2 can be accomplished by two
separate methods—EEPROM evaluation and in-circuit emulator (ICE)
evaluation. Use of the EEPROM installed on the board is recommended when
performing a quick initial check to verify if the board works properly. The
respective evaluation procedures are detailed in the following section.
1.1.1 EEPROM Evaluation (Internal Mode)
The TUSB3200EVM2 comes with a preprogrammed EEPROM. This
EEPROM is inserted in the 8-pin DIP socket. The jumper configuration for the
internal mode is listed in T able 1–1. Use the following procedure for EEPROM
evaluation:
-
Set J8 to position 1–2 to bus-power the TUSB3200EVM2; set J8 to 2–3
to put the TUSB3200EVM2 in self-powered mode (a power supply is
required).
-
In self-powered mode, a single 9-V dc at 500-mA supply must be
connected to the power terminals 9V and ground (GND) of the
TUSB3200EVM2. Once the board is powered, GPIO, and the LEDs
should turn on, and the power drawn from the supply should not exceed
the USB specification of 500 mA.
-
Connect a USB cable from the root hub of the PC to type-B connector J1
on the EVM. This should start the USB enumeration on a host PC.
Enumeration signals that a USB (audio) device has been detected by the
1-2
host PC and the device is ready to stream audio via a USB. A speaker icon
should show up once the enumeration is complete. Double click this icon
to confirm that the USB is the preferred device for audio output; if not,
reconfigure the PC for USB audio output.

1.1.2 In-Circuit Emulator (ICE) Evaluation
Use the following procedure for in-circuit emulator evaluation:
-
Install the emulator. Refer to the respective ICE user’s guide for the emula-
tor.
-
Attach emulator POD to TUSB3200EVM2 ICE Socket (J3). A 40-pin extension adapter may be required to allow enough clearance for access to
the buttons, jumpers, and connectors. Pin 1 is designated by a triangle on
the opposite side of the J3 reference designator.

TUSB3200EVM2 Setup
2.1 TUSB3200EVM2 Setup
The TUSB3200EVM2 is designed to allow development and evaluation of the
TUSB3200A for multichannel applications. The USB controller (U1) accepts
USB data streams and generates output at the C-port, I2C port, and/or GPIO
port. A full explanation of how to configure the TUSB3200A to control the
streaming data and set up the interface ports and registers is contained in the
TUSB3200A data manual. A standard USB cable is required to connect the
EVM platform to a downstream port. The EVM uses a standard type-B
connector. Set JP8 to position 2–3 to send the MCLKO to the codec. Set JP3
to position 2–3 for normal mode operation; this action disables the external
interrupt signal to the TUSB3200A. Note that an arrow always designates
position 1 of any jumper. The TUSB3200A must be set to external mode to use
the in-circuit emulator. The TUSB3200EVM2 board is shipped in internal
mode. For internal mode, JP4 is open and JP15 is closed. T o switch to external
mode, simply move the jumper from JP15 to JP4.
2.2 Interfaces and Ports
The USB port interface is the only connection required for full operation. The
in-circuit emulator is required for the external emulator pad. All other
connections are used to increase further development and evaluation
functionality. The USB connector has four pins defined as VBUS (pin 1), D+
(pin 2), D– (pin 3), and GND (pin 4).
2.3 Power Supplies
The TUSB3200EVM2 board can be self-powered, or can use USB bus power
(when J8 is set to position 2–3). In the self-powered mode, the
TUSB3200EVM2 PCB requires a single positive 9-V dc supply at 500 mA. An
LM317EMP regulator is used to generate a steady 5-V dc supply . This 5-V dc
supply is connected to an onboard, low-dropout regulator to generate a 3.3-V
dc supply. In the USB bus-powered mode, connect one end of a USB cable
to the EVM board and another end of the cable to a PC root port.
2.4 Light Emitting Diode (LED)
A set of green and yellow LEDs is installed on the TUSB3200EVM2 board for
quick and easy GPIO evaluation. The green LEDs are connected to port 1 bits
0 through 7 of the in-circuit emulator for external mode. The yellow LEDs are
connected to port 1 bits 0 through 7 and port 3 bits 0, 1, and 3–5 of the
TUSB3200A for normal mode. Note that yellow LEDs illuminate in external
mode but are not GPIO functions and should not be treated as such.

Complete Analog Stage
2.6 Complete Analog Stage
A complete analog output stage is provided on the TUSB3200EVM2 platform
to eliminate the need for back-end development for evaluation purposes. The
analog stage includes a crystal CS4228 codec and line output amplifiers with
second-order low-pass filters for all six channels. A line input and a line output
are also provided.
2.7 EEPROM
The EEPROM is used to set up the TUSB3200EVM2. The EEPROM is
recommended to be 8K bytes to match the RAM memory size. Firmware for
the TUSB3200EVM2 must be loaded for correct operation. An 8-pin DIP
socket allows easy installation and removal of the EEPROM. TUSB3200A
automatically downloads the data from the EEPROM into memory and begins
executing code once the board is powered up and connected to the host via
the USB.
