The TLV320AIC1106EVM is an Evaluation and Demonstration Board and Kit for the TLV320AIC1106 – a high-performance, low-power Audio CODEC with integrated capacitive-touch button control. This board utilizes the TLV320AIC1106 CODEC (with the device-specific configuration) along with a host of external components to enable system level evaluation and development. It has an audio interface with a stereo headphone jack and mono Speaker-out, as well as a graphical user interface for accessing and controlling the CODEC’s features. The board is compact, measuring just 4.9 x 4.2 inches (125mm X 110mm), and is RoHS compliant.

Application Field

The TLV320AIC1106EVM is ideal for audio test and development in a range of applications, including automotive audio systems, audio products, NIC cards, and mobile phones. The combination of the tiny size of the TLV320AIC1106 CODEC and the wide variety of options offered (such as the graphical user interface) makes this board suitable for those needing to optimize their designs for high-performance audio with minimum component effort.

Working Principle

The TLV320AIC1106EVM is composed of the TLV320AIC1106 CODEC, a 16-button control interface, and a 4-layer printed circuit board. The CODEC operates up to a 24-bit sampling rate of 48kHz, with a 192kHz Passband. It supports dual-channel digital and analog audio, as well as multi-channel digital audio (8-channel PCM and 6-channel I2S), allowing for a wide variety of applications in the digital and analog audio domains. The CODEC can be controlled via either I2C or SPI interfaces, enabling it to be connected to other devices to send and receive digital audio data. The TLV320AIC1106EVM is also equipped with a 16-button touch control interface, allowing users to control and modify the CODEC settings as required.

The TLV320AIC1106EVM is powered by two single-supply, 3.3V power supplies and can accept both AC and DC power sources. The CODEC is able to be powered up at voltages in excess of 5V, which makes it suitable for applications where the source voltage is non-regulated. The board also includes an on-board USB-UART, allowing for connection to a PC for remote control and debugging. Additionally, the board provides access to several external memory interfaces, allowing for connection to external memories such as NAND flash, EEPROM, and NOR flash.

The TLV320AIC1106EVM comes with an onboard software package that allows the user to interact with the board and control the CODEC settings. This package includes software drivers, sample application code, and sample data. The drivers can be used to control the CODEC settings, as well as provide access to an integrated graphical user interface (GUI) and diagnostic tool for viewing and manipulating the board configuration. The software package also includes support for I2C and SPI operations, allowing for integration with external devices.

In conclusion, the TLV320AIC1106EVM is an Evaluation and Demonstration Board and Kit that simplifies system level evaluation and development. It is compact and includes a wide range of features, making it suitable for use in a wide variety of audio applications. Additionally, the board comes with an integrated software package for quickly and easily controlling and manipulating the CODEC settings, as well as providing access to a graphical user interface.
