Description
Bill of Materials ...................................................................................... 8
The TPA5052 evaluation module (EVM) consists of a single TPA5052 audio delay device, along with other
external components mounted on a printed-circuit board (PCB). It can be used to digitally delay both
channels by up to 8191 samples (with a 48-kHz sampling rate, that equates to more than 170 ms of
delay).
The TPA5052EVM is designed so that analog music can be input to the board. The music is converted to
I2S digital format where the TPA5052 delays it. The music then is converted back to analog where it is fed
to the TPA4411 audio amplifier. The output of the TPA4411 is connected to a 3.5-mm stereo headphone
jack. A simple pair of stereo headphones are all that are required to listen to the music. This allows the
user to quickly and easily use the TPA5052EVM to delay the television audio to synchronize with the
video. Probe points also are provided.
Additional evaluation may be performed with small modifications that allow for direct interaction with the
TPA5052 in I2S format.

Power Supply
1.
Ensure that all external power sources are set to OFF.
2.
Connect an external regulated power supply set to 5 V to the module +5V (J8) and GND (J9),
taking care to observe marked polarity.
EVM Preparation
3.
Ensure that the shunts are open on jumpers J3 through J7. This jumper setting sets the TPA5052
to operate with minimum delay. If more delay is required, shunt the appropriate jumpers. See the
TPA5052 data sheet for more information about delay settings.
4.
Connect a cable from a music source, such as a CD player, to input jack J1. Insert headphones
into output jack J2.
Operation
5.
Turn on the power supply for the TPA5052EVM.
6.
The Power On LED glows green, indicating that the EVM has adequate power.
7.
Start playing music with the music source.
8.
Place headphones on head and listen to the music.

Advanced Features
The TPA5052EVM is designed to allow for extensive evaluation of the TPA5052. Removing a few
components allows for direct access to the TPA5052 and measurement of the delay.
3.1
Configuration for Advanced Measurements
If the need arises to directly evaluate the TPA5052 with digital data, follow these steps.
1. Ensure that no power supply or signal cables are connected to the TPA5052EVM.
2. Locate and remove resistors R14 and R15 on layer four of the PCB.
3. Locate and remove resistor R16 on the top layer of the PCB.
4. Connect LRCLK of the source to J10. Be sure to ground the accompanying LRCLK ground to the
adjoining GND pin for optimal performance
5. Connect BCLK of the source to J11. Be sure to ground the accompanying BCLK ground to the
adjoining GND pin for optimal performance
6. Connect DATA of the source to J12. Be sure to ground the accompanying DATA ground to the
adjoining GND pin for optimal performance
7. Connect the DATA_OUT pin J13 and the associated GND to the measurement device.
8. Connect an external regulated power supply set to 5 V to the module +5V (J8) and GND (J9), taking
care to observe marked polarity.
9. Turn on digital audio source.
10. The delay is changed by closing or opening jumpers J3 through J7, and measuring the output with
respect to the input.

SELLER TO BUYER AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING
ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE.
The user assumes all responsibility and liability for proper and safe handling of the goods. Further, the user indemnifies TI from all
claims arising from the handling or use of the goods. Due to the open construction of the product, it is the user’s responsibility to
take any and all appropriate precautions with regard to electrostatic discharge.
EXCEPT TO THE EXTENT OF THE INDEMNITY SET FORTH ABOVE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER
FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES.
TI currently deals with a variety of customers for products, and therefore our arrangement with the user is not exclusive.
TI assumes no liability for applications assistance, customer product design, software performance, or infringement of
patents or services described herein.
Please read the User’s Guide and, specifically, the Warnings and Restrictions notice in the User’s Guide prior to handling the
product. This notice contains important safety information about temperatures and voltages. For additional information on TI’s
environmental and/or safety programs, please contact the TI application engineer or visit www.ti.com/esh.
No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or
combination in which such TI products or services might be or are used.
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 voltage supply range of 4.5 V to 5.5 V.
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.
