For use with the TLV320AIC3104EVM, SW-2 positions 1 through 7 should be set to ON, while SW-2.8 should be set to OFF. Table 1. USB-MODEVM SW2 Settings SW-2 Switch Number Label Switch Description 1 A0 USB-MODEVM EEPROM I2C Address A0 ON: A0 = 0 OFF: A0 = 1 2 A1 USB-MODEVM EEPROM I2C Address A1 ON: A1 = 0 OFF: A1 = 1 3 A2 USB-MODEVM EEPROM I2C Address A2 ON: A2 = 0 OFF: A2 = 1 4 USB I2S I2S Bus Source Selection ON: I2S Bus connects to TAS1020 OFF: I2S Bus connects to USB-MODEVM J14 5 USB MCK I2S Bus MCLK Source Selection ON: MCLK connects to TAS1020 OFF: MCLK connects to USB-MODEVM J14 6 USB SPI SPI Bus Source Selection ON: SPI Bus connects to TAS1020 OFF: SPI Bus connects to USB-MODEVM J15 7 USB RST RST Source Selection ON: EVM Reset Signal comes from TAS1020 OFF: EVM Reset Signal comes from USB-MODEVM J15 8 EXT MCK External MCLK Selection ON: MCLK Signal is provided from USB-MODEVM J10 OFF: MCLK Signal comes from either selection of SW2-5 Table 2 provides a list of jumpers found on the EVM and their factory default conditions. Table 2. List of Jumpers Default Jumper Position Jumper Description JMP1 2-3 When connecting 2-3, mic bias comes from the MICBIAS pin on the device; when connecting 1-2, mic bias is supplied from the power supply through a resistor, which the user must install. JMP2 Installed Connects onboard Mic to Left Microphone Input. JMP3 Installed Connects onboard Mic to Right Microphone Input. JMP4 Installed Provides a means of measuring IOVDD current. JMP5 Installed Provides a means of measuring AVDD_ADC current. JMP6 Installed Provides a means of measuring DVDD current. JMP7 Installed Provides a means of measuring DRVDD current. JMP8 Installed Provides a means of measuring AVDD_DAC current. JMP9 Installed Connects Analog and Digital Grounds. JMP10 3-5 When connecting 3 to 5, I2C is selected as control mode; when connecting 1 to 3, SPI is selected as control mode. When connecting 3 to 4, mode selection can be made by a logic level at J16.12 JMP11 3-5 In I2C control mode, this jumper sets the state of A0. When connecting 3 to 5, A0 = 0; when connecting 1 to 3, A0 = 1. In SPI control mode, connecting 3 to 4, SPI /SS is provided from J16.2 JMP12 3-5 In I2C control mode, this jumper sets the state of A1. When connecting 3 to 5, A1 = 0; when connecting 1 to 3, A1 = 1. In SPI control mode, connecting 3 to 4, SPI SCLK is provided from J16.3 JMP13 Installed When installed, shorts across the output capacitor on HPLOUT; remove this jumper if using AC-coupled output drive SLAU218 – August 2007 TLV320AIC3104EVM and TLV320AIC3104EVM-PDK 5 Submit Documentation Feedback |
