An IMPORTANT NOTICE at the end of this TI reference design addresses authorized use, intellectual property matters and otherimportant disclaimers and information.

1 Quick Start Guide

1.1 Getting Started HardwareRequired hardware for a demonstration of the audio adapter accessory mode:• TIDA-00565 demo board.• 19 V barrel jack power supply for the TIDA-00565 board.• An audio source such as a PC or a smart phone.• Cable with a 3.5 mm male jack to a 3.5 mm male jack to interface the audio source to the 3.5mm jack

on the TIDA00565 board• Pair of headphones or speaker• USB Type-C audio adapter with a 3.5 mm female jack to a USB Type-C male connector. (not needed if

an audio headset or speaker with a USB Type-C connector is available)

1.2 Getting Started Procedure1. Plug in a 19 V power supply into the barrel jack of the TIDA-00565 board which provides power.2. Plug in an audio source into the 3.5 mm jack of the TIDA-00565 board.3. Plug in a pair of headphones and a speaker with a USB Type-C connector, or use the audio adapter

board to interface the headphones and speaker with a 3.5 mm jack to USB Type-C Connector.

1.3 Purpose of TS5USBA224The TS5USBA224 is used to multiplex between the USB 2.0 data and analog audio in order to protect theUSB PHY from the negative voltage swings of the analog audio. The analog audio and USB data travelover the D+ and D- lines in the USB Type-C connector. When an analog audio signal is on the USB D+and D- lines, the signal may swing up to –2 to 2 Vpp. This negative swing in voltage can cause damage tocomponents in the signal chain that may not be able to handle a negative swinging signal.

The TS3A227E is used specifically to automatically detect and orient the MIC and GND signals of the 3.5mm jack to support the function described in the USB Type-C standard above. Refer to the TS3A227EAutonomous Audio Accessory Detection and Configuration Switch datasheet (SCDS358B) for more detailson the automated detection. The USB Type-C to 3.5 mm dongle is on the sink side of the system,therefore, the system user may connect speakers or a headphone set to listen to the audio. Headphonesoften come with a 4-pole jack, which means the MIC and GND of the jack must be routed properly.

1.4 Purpose of the TS3A227EThe USB Type-C standard states, “The system shall connect A6/B6, A7/B7, A8 and B8 to an appropriateaudio codec upon entry into the audio adapter accessory mode. The connections for A8 (SBU1) and B8(SBU2) pins are dependent on the adapter’s orientation. Depending on the orientation, the microphoneand analog ground pins may be swapped. These pins are already reversed between the two majorstandards for headset jacks and support for this is built into the headset connection of many codecs, ormay be implemented using an autonomous audio headset switch. The system works correctly with eitherconfiguration."

1.5 Purpose of the TUSB321X / TPS65982The TUSB32X or TPS65982 device enables USB Type-C ports with the configuration channel (CC) logicneeded for USB Type-C ecosystems. The TUSB32X/TPS65982 device use the CC pins to determine thetype of device inserted into the USB Type-C connector. When the TUSB32X/TPS65982 device sees anaudio accessory (by sensing the Ra 1k pull down resistors on the accessory) it can use one of its GPIOsto toggle the TS5USBA224 logic control pins to select the audio path of the TS5USBA224.

2 Design OverviewThe USB Type-CTM audio adapter accessory mode reference design provides the solution for interfacinganalog audio through the emerging USB Type-C interface. This reference design demonstrates howanalog audio may be transmitted to system peripherals using the USB Type-C standard’s audio adapteraccessory mode. This allows designs to remove the large 3.5 mm jack, and replace it with an 85% smallerUSB Type-C receptacle.

4 System DescriptionThe USB Type-C audio adapter accessory mode reference design is composed of two boards; a USBType-C analog audio multiplexer board and a USB Type-C connector to a 3.5 mm jack adapter. The USBType-C analog audio multiplexer board controls the switching between analog audio transferred throughthe USB Type-C connector and data transferred through the USB Type-C connector. The USB Type-C to3.5 mm jack adapter board provides the required pull down resistors for the USB Type-C presence detectlogic on CC1 and CC2 that signifies an audio adapter is being used. The adapter also allows users to testaudio with existing audio devices that use the 3.5 mm jack interface.

5 Block DiagramThe USB-C Analog Audio TI Design allows for analog audio to be passed over USB Type-C connectionwhile protecting the USB PHY from negative voltages swings from the analog audio. In Figure 3, the audiosource may be produced through a computer, while the audio sink may be a speaker to listen to the audio.Figure 3 shows the TIDA00565 functional block diagram.

System Design Theory www.ti.com




6 System Design TheoryThis TIDA00565 system is designed to prove in a simple demonstration how analog audio may be passedover USB Type-C connector. Left and right analog audio is passed through the USB-C connector throughthe D+ and D- lines of the USB Type-C connector. Simply passing audio through USB-C is possiblewithout the use of ICs, but it is not practical as the negative signal swing of the audio signal can damageother components in the system. The TS5USBA224 provides the ability to pass analog audio withoutallowing the negative signal swing of the audio damage any other parts of the system

6.1 USB Type-C Audio Adapter Accessory ModeAnalog audio headsets are supported by multiplexing four analog audio signals onto pins on the USBType-C ™connector when in the audio adapter accessory mode. The audio adapter accessory mode isdeclared to the host by placing two (Ra) pull down resistors on the CC1 and CC2 pins. These resistors onthe CC lines are dictated by the USB Type-C specification.

The four analog audio signals are the same as those used by a traditional 3.5 mm headset jack. Thisadapter makes it possible to interface existing analog headsets with a 3.5 mm to USB Type-C adapter forthis demonstration. The adapter also provides the two 1k ohm (Ra) pull down resistors.Figure 4 shows theexample schematics of a passive 3.5 mm jack to the Type-C connector adapter.

Total Harmonic Distortion Measurement (THD+N) www.ti.com




7 Total Harmonic Distortion Measurement (THD+N)The Total Harmonic Distortion (THD) for the TIDA-00565 was measured using SYS-2722 (192k) AudioPrecision equipment. A 1-V pp sine wave was sent through the D+ and D- lines of the USB Type-Cconnector, while the TS5USBA224 device audio path was selected. A 600-Ω load was provided by theaudio precision equipment as shown in Figure 34, the THD+N test set up screen shot in .

Appendix A

A.1 TS5USBA224The TS5USBA224 USB 2.0 and audio switch is used to multiplex between the USB 2.0 data and analogaudio. The switch is a FET-based switch, which is optimized with low On-resistance to maintain signalintegrity. The USB 2.0 path has a bandwidth of up to 650 MHz signals. The audio path features a THD+Nof less than 0.05% and includes shunt resistors to reduce clicks and pops that may be heard when theaudio switch is selected by dissipating residual charge that could be on the audio path. The TS5USBA224switch is used to protect other components on the D+ and D- lines from analog audio signals that swing toa negative voltage. Figure 9 shows the functional block diagram of the TS5USBA224.

A.2 TS3A227EThe TS3A227E audio jack switch is used to automatically route the MIC and GND signals appropriately.There are three types of audio jacks that may be inserted into the 3.5 mm audio jack. One of the threeaudio jacks is a 3-pole jack, containing left and right audio, and GND. Two of the three audio jacks are 4-pole jacks, containing the left and right audio, MIC, and GND. For the 4-pole jacks, the MIC and GND maypotentially be swapped, depending on the manufacture of the audio jack. Thus, the TS3A227E detects thecorrect location of both MIC and GND on the 4-pole audio jack and routes the GND properly to GND andMIC to the desired location.

A.3 TPS65982The TPS65982 function as a power delivery IC for USB Type-C. In the case of this USB Type-C analogaudio TI Design, the TPS65982 is used for its accessory detection feature on the CC1 and CC2 pins ofthe USB Type-C connector. TI offers other smaller products that soley provide the accessory detectionfeature such as the TUSB32X series of devices. After the TPS65982 detects the impedance of Ra (800 Ω< Ra < 1.2 kΩ), a GPIO on the TPS65982 configures the TS5USBA224 to the audio pathway. If theTPS65982 detects the impedance not equal to Ra, the GPIO configures the TS5USBA224 to the USBpathway. When a non-audio peripheral is attached to the USB-C, the TPS65982 performs its full functionas a power delivery IC. Figure 11 shows the functional block diagram of the TPS65982.
