Installation
This section describes the software and EVM installation.
3.1 Software Installation
Execute the GUI install program setup.exe, found in the TAS570x GUI directory in the provided compact
disc. Once the program is installed, the program group and shortcut icon is created in Start → Program
→Texas Instruments Inc → TAS570x Interface.
3.2 EVM Installation
The following are the basic tools for the initial EVM power up.
•
•
•
•
•
•
•
•
5 V, 1 A power supply (VIN)
10–26 V, 4 A power supply (PVDD)
Banana-style test leads for power supplies and speakers
Optical cable for SPDIF interface based on signal source
Coaxial cables with phono plugs for analog audio if digital audio is unavailable
USB cable
EVM software
Two 8-Ω speakers or loads
The following sections describe the TAS5601EVM board in regards to power supply (PSU) and system
interfaces.
3.2.1
PSU Interface
The TAS5601EVM module is powered by two power supplies connected to the MC5601 controller board:
a 5-V power supply (VIN) and a 10-V to 26-V (PVCC) power supply. The 3.3-V level is generated on the
board by a voltage regulator from the 5-V supply.
Note: The power-supply cable length must be minimized. Increasing the length of the PSU cable
increases the distortion of the amplifier at high output levels and low frequencies.

Installation
•
Connect the left speaker wires to the corresponding metal binding posts marked J2 and J4 on the
TAS5601EVM board.
•
Connect the right speaker wires to the corresponding metal binding posts marked J6 and J8 on
TAS5601EVM board.
For SE:
•
Connect the four sets of speaker wires to the pairs J2-J3, J4-J5, J6-J7, and J8-J9.
3.2.3
USB Interface
The TAS5601 registers are accessed through I2C bus lines SDA and SCL. The USB circuit and USB
connector on the MC5601 board facilitates the connection between a host computer and the device. The
EVM USB circuit is powered by the 5-V USB line of the host PC, and is independent of the power supplies
available on the board. The USB device used is a TAS1020B from Texas Instruments.
3.2.4
3.2.5
3.2.6
Digital Audio Interface SPDIF (J1/OPTO)
The Digital Audio Interface accepts digital audio data using the I2S protocol. See the TAS5706 data sheet
for more information.
The OPTO connector is the SPDIF interface on the MC5601 board. When the optical cable is connected
and the signal source is powered up, verify that the SPDIF lock indicator (blue LED3) illuminates,
confirming that there is a viable signal available to the device. Install the four clock/data jumpers across
the middle pin and the pin marked SPDIF.
For detailed information on how the data and clocks are provided to the TAS5601, see the schematic
ADC Interface
In the absence of a digital signal source, the PCM1808 ADC may be used to convert an analog audio
signal to a digital signal to the TAS5601. The DIR9001 still provides clock signals to the ADC in this
process. The DIR9001 oscillator frequency (Y2) determines the sampling frequency in the absence of a
digital signal. If the OSC frequency is 24 MHz, the sampling frequency is set at 96 kHz; if OSC is set at 12
MHz, the sampling frequency defaults to 48 kHz when there is no signal on the SPDIF input terminals. A
12-MHz crystal is installed on the MC5601 board. The ADC is an additional feature of this board to
detailed description of the ADC on this EVM. Install the jumper on SDW2 across the middle pin and the
pin marked ADC.
Board Power-Up General Guidelines
Connect the MC5601 and the TAS5601EVM boards by locating pin 1 on each board, indicated by a small
white triangle. The TAS5601EVM plugs into the MC5601 board. Pin 1 on each board should be connected
to each other.
Install the EVM software on the PC before powering up the board. After connecting the loudspeakers or
other loads, power supplies, and the data line, power up the 5-V power supply first; then power up the
PVDD power supply. It is recommended initially to set the PVDD level to 10 V, then ramp it up to 20 V to
verify cable connections.

FCC Warning
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES
ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and can radiate radio
frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15 of FCC rules, which are
designed to provide reasonable protection against radio frequency interference. Operation of this equipment in other environments may
cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may
be required to correct this interference.
EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the input voltage range of -0.5 V to 4.1 V and the output voltage range of 1 Vrms.
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions
concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM.
Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification,
please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 85°C. The EVM is designed to operate
properly with certain components above 85°C as long as the input and output ranges are maintained. These components include but are
not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified
using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation,
please be aware that these devices may be very warm to the touch.
