EVM Overview

1 EVM Overview

1.1Features

Full-featuredevaluation board for the TLV320AIC12K/14K audio codec

TLV320AIC12KEVMB-K/14KEVMB-Kfeatures USB connectivity for quick and easy setup.

Intuitive evaluation software

Easy interfacing to multiple analog sources

Analog output signals from the TLV320AIC12K/14K are available on top and bottom connectors.

On-boardheadphone jack, external microphone jack and electret microphone are included

Digital control signals can be applied directly to top and bottom connectors.

1.2Introduction

The TLV320AIC12KEVMB-K/14KEVMB-Kis a complete evaluation/demonstration kit, which includes aUSB-basedmotherboard called theUSB-MODEVMInterface board and evaluation software for use with a personal computer running Microsoft Windows® operating systems. Provisions are made for connecting all audio inputs and outputs either from the modular connectors or withon-boardterminals, a headphone jack, and external microphone jack. Anon-boardelectret microphone is also provided.

2Analog 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-KandTSM-110-01-T-DV-Pprovide a convenient10-pindual row header/socket combination at J1 and J2. These headers/sockets provide access to the analog input and output pins of the device. Consult Samtec atwww.samtec.com or call1-800-SAMTEC-9for a variety of mating connector options.Table 1 summarizes the analog interface pinout for the TLV320AIC12KEVMB/14KEVMB.

In addition to the analog headers, the analog inputs and outputs may also be accessed through alternate connectors, either screw terminals or audio jacks. The microphone input is also tied to J8 and the headset output tied to J11. Table 2 summarizes the screw terminals available on the TLV320AIC12KEVMB/14KEVMB.
