  • Page 3: Evm Overview

    An on-board electret microphone is also provided. Analog Interface For maximum flexibility, the TLV320AIC12KEVMB/14KEVMB is designed for easy interfacing to multiple analog sources. Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin dual row header/socket combination at J1 and J2. These headers/sockets provide access to the analog input and output pins of the device.

    INP1 Digital Interface The TLV320AIC12KEVMB/14KEVMB is designed to easily interface with multiple control platforms. Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin dual row header/socket combination at J4 and J5. These headers/sockets provide access to the digital control and serial data pins of the device.
  • Page 5 The reset and power down (RESET and PWRDN) signals are routed to J4. I C™ is actually routed from the USB-MODEVM to both connectors; however, the codec and EEPROM are only connected to J5.

  • Page 6: Power Supplies

    IOVDD (3.3V) J3.9 J3.10 The TLV320AIC12KEVMB-K/14KEVMB-K motherboard (the USB-MODEVM Interface board) supplies power to J3 of the TLV320AIC12KEVMB/14KEVMB. Power for the motherboard is supplied either through its USB connection or via terminal blocks on that board. Stand-Alone Operation When used as a stand-alone EVM, power can be applied to J3 directly. The user must be sure to reference the supplies to the appropriate grounds on that connector.

  • Page 7: Kit Operation

    The digital control signals can be applied directly to J4 and J5 (top or bottom side). The modular TLV320AIC12KEVMB/14KEVMB can also be connected directly to the USB-MODEVM Interface board included as part of the TLV320AIC12EVMB-K/14EVMB-K. See the product folder for this...

TLV320AIC12KEVMB-K/14KEVMB-K Block Diagram 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, PCM/SMARTDM™) externally.

  • Page 14 The Device Position control lets the user select a specific codec on a master-slave chain to write to or read from. The TLV320AIC12KEVMB-K/14KEVMB-K is configured as a stand-alone slave, so the device position must be set to zero. The Program Device button, when pushed, programs the register corresponding only to the selected Control Registers sub tab.
