Installation
2.1.1
Connecting the TAS5727EVM to MC57xxPSIA
On the right side of the MC57xxPSIA is a terminal block and another on the left of the TAS5727EVM
(labeled J1). Carefully place the MC57xxPSIA block above the TAS5727EVM block and gently push down.
Figure 4. Connecting TAS5727EVM to MC57xxPSIA
PSU Interface
2.1.2
The TAS5727EVM is powered by two power supplies connected to the MC57xxPSIA controller board: a
5V power supply (VIN), and a 8V-to-26V (PVDD) power supply. The 3.3V level is generated from the 5V
supply by an on-board voltage regulator.
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.
The maximum output-stage supply voltage depends on the speaker load resistance. See the
recommended maximum supply voltage in the TAS5727EVM data sheet.

Loudspeaker Connectors
CAUTION
All speaker outputs are biased at Vcc/2 and must not be connected to ground
(e.g., through an oscilloscope ground).
Loudspeaker connections vary by device setup. When connecting a speaker in BTL mode, connect the
speaker’s two terminals (A and B or C and D) across two outputs on the TAS5727EVM.
Speakers or loads can be connected to the outputs A-D with clip leads, or cables can be made
with female connectors (JST VHR-2N) that can mate to male connectors on the EVM board.

USB Interface
The TAS5727 registers are accessed through I2C™ bus lines SDA and SCL. The USB circuit and USB
connector on the MC57xxPSIA board facilitates the connection between a host computer and the device.
The EVM USB circuit is powered by the 5V USB line of the host PC and is independent of the power
supplies available on the board. The USB device that is used is a TAS1020B from Texas Instruments.
Digital Audio Interface SPDIF
The Digital Audio Interface SPDIF (RCA/OPTO) accepts digital audio data using the I2S protocol. See the
TAS5727 data sheet for more information.
The RCA connector and the OPTO connector are the two SPDIF interfaces on the MC57xxPSIA board.
The switch S3 toggles between the OPTO and RCA connector to accommodate the signal source. When
the RCA cable or optical cable is connected and the signal source is powered up, verify that the SPDIF
lock indicator (blue LED5) illuminates, confirming that a viable signal is available to the device. Install a
jumper on JP4 across the middle pin and the pin marked SPDIF to connect the digital source to SDIN1.
Install a jumper on JP5 to connect the digital source to SDIN2.
For detailed information on how the data and clocks are provided to the TAS5727, see the schematic
2.1.6
2.1.7
ADC Interface
In the absence of a digital signal source, the PCM1808 ADC can be used to convert an analog audio
signal to a digital signal to the TAS5727. The DIR9001 still provides clock signals to the ADC in this
process. A 12MHz crystal is installed on the MC57xxPSIA board. The ADC is an additional feature of this
board to provide flexibility in sourcing an audio signal to the TAS5727. Review the PCM1808 data sheet
(SLES177) for a detailed description of the ADC on this EVM. Install the jumper on JP4 across the middle
pin and the pin marked ADC to select ADC as the source for SDIN1.
Board Power-Up General Guidelines
Connect theMC57xxPSIA and the TAS5727EVM boards by locating pin 1 on each board, indicated by a
small white triangle. TheMC57xx plugs down onto the TAS5727EVM board (i.e., the TAS5727EVM board
fits underneath the MC57xxPSIA board). Pin 1 on each board must 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 5V power supply first; then power up the
PVDD power supply. It is recommended initially to set the PVDD level to 10V, then ramp it up to 20V to
verify cable connections.
2.2 Software Installation
Download the TAS57x UI from the TI Web site. The TI Web site always has the latest release and any
updates to versions of the GUI.

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 -0.5V to 4.1V and the output voltage range of 26Vp-p.
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.
