User's Guide SLOU335 – May 2012 TAS5414B and TAS5424B Evaluation Module (EVM) User's Guide The TAS5414B/TAS5424B evaluation module (EVM) is intended to be used to demonstrate the capabilities of the device. All the device features can be accessed through the hardware and the software graphical user interface (GUI) supplied. This user’s guide contains a description of the EVM and the GUI. Included are the EVM schematics, bill of materials, and the board layout.
Quick-Start Guide 1.2 www.ti.com Software Installation The software is provided on the TI Web site. Run the setup.exe program to install the GUI. For more details, see Section 1.5, Basic Graphical User Interface Controls. 1.3 Connections The connections are for an analog signal for the input, speaker loads, power, and I2C. The audio inputs are made through the four RCA connectors. The power connectors and speaker connectors are made using the 10-pin connector.
EVM Description www.ti.com Apply power: the Standby, Mute, and Power LEDs should be on. The Fault LED may also be on, but not necessarily. This indicates that the unit is powered, and the TAS5414B or TAS5424B is in Standby Mode and Mute Mode. The fault indicated is an undervoltage fault during power up. This is normal and is cleared by reading I2C Register 0x00 (the Read Faults button) twice. Reading the faults once clears the faults, and the second read is to ensure that all the faults have been cleared.
EVM Description www.ti.com The speaker connections consist of the remaining four pairs of red and white twisted wire. Each pair of red and white wires corresponds with a channel. The red wire corresponds to the plus (+) output, and the white wire corresponds to the minus (–) output. These wires must be terminated to a speaker load or resistive load.
Graphical User Interface www.ti.com 2.4 Indicator Description There are five LED indicators on the chassis next to the standby switch. The LED farthest away from the standby switch is for the 3.3 Vdc supply. The 3.3 V supply is needed for the LEDs and the standby circuit. The other four LEDs indicate the four non-I2C output pins: FAULT , CLIP_OTW, STANDBY, and MUTE. The FAULT and CLIP_OTW signals are also routed to the 6-pin DIN for the GUI. In normal play mode, these four LEDs should not light.
Graphical User Interface 3.4.2 www.ti.com Device Status Panel Device Panel Title: The title at the top of the Device Status Panel shows which device the GUI is set to communicate. The four options are: Master, Slave1, Slave 2, and Slave 3. This is changed in the menu item Device Select. Global: This provides fault feedback from the device. If a fault occurs a red Fault is indicated. Read the fault detail in the register 0x00 and 0x01. Temperature: This shows the temperature of the device.
TAS5414/TAS5424B EVM Schematics www.ti.com Preloaded Macros: This menu item provides a list of built-in macros to perform typical I2C routines. Read: The Read panel controls are located in this menu Fault Registers: When selected, the values of the fault registers are displayed in the I2C log. Note that reading fault registers is different from reading faults. The data in a fault register is cleared on read.
