EVM Description and Basics
TLV320AIC3104EVM-PDK Block Diagram
• Full-featured evaluation board for the TLV320AIC3104 stereo audio codec.
• Modular design for use with a variety of digital signal processor (DSP) and microcontroller interface
• USB connection to PC provides power, control, and streaming audio data for easy evaluation.
• Onboard microphone for ADC evaluation
• Connection points for external control and digital audio signals for quick connection to other
The TLV320AIC3104EVM-PDK is a complete evaluation kit, which includes a universal serial bus
(USB)-based motherboard and evaluation software for use with a personal computer (PC) running the
Microsoft Windows™ operating system (Win2000 or XP).
The TLV320AIC3104EVM is in the Texas Instruments modular EVM form factor, which provides direct
evaluation of the device performance and operating characteristics, and eases software development and
system prototyping. This EVM is compatible with the 5-6K Interface Evaluation Module (SLAU104) and the
HPA-MCUINTERFACE (SLAU106) from Texas Instruments and additional third-party boards which
support the Texas Instrument modular EVM format.
The TLV320AIC3104EVM-PDK is a complete evaluation/demonstration kit, which includes a USB-based
motherboard called the USB-MODEVM Interface board and evaluation software for use with a personal
computer running the Microsoft Windows operating systems.
The TLV320AIC3104EVM-PDK is operational with one USB cable connection to a personal computer. The
USB connection provides power, control, and streaming audio data to the EVM for reduced setup and
configuration. The EVM also provides external control signals, audio data, and power for advanced
operation, which allows prototyping and connection to the rest of the development or system evaluation.
This section provides information on the analog input and output, digital control, power and general
connection of the TLV320AIC3104EVM.
The TLV320AIC3104EVM-PDK consists of two separate circuit boards, the USB-MODEVM and the
TLV320AIC3104EVM. The USB-MODEVM is built around a TAS1020B streaming audio USB controller
with an 8051-based core. The motherboard features two positions for modular EVM, or one double-wide
serial modular EVM may be installed. The TLV320AIC3104EVM is one of the double-wide modular EVM
that is designed to work with the USB-MODEVM.
The simple diagram below (Figure 1) shows the how the TLV320AIC3104EVM is connected to the
USB-MODEVM. The USB-MODEVM Interface board is intended to be used in USB mode, where control
of the installed EVM is accomplished using the onboard USB controller device. Provision is made,
however, for driving all the data buses (I
C, SPI™, I
S/AC97) externally. The source of these signals is
controlled by SW2 on the USB-MODEVM. Refer to Table 1 for details on the switch settings.
The USB-MODEVM has two EVM positions that allow for the connection of two small evaluation module
or one larger evaluation module. The TLV320AIC3104EVM is designed to fit over both of the smaller
evaluation module slots as shown below.
