EVM Overview
1 EVM Overview
1.1 Features
Full-featured evaluation board for the TLV320AIC11xx audio codec
TLV320AIC11xxEVM-K features USB connectivity for quick and easy setup.
Intuitive evaluation software
Easy interfacing to multiple analog sources
Analog output signals from the TLV320AIC11xx are available on top and bottom connectors.
External microphone jack and electric microphone are included
Digital control signals can be applied directly to top and bottom connectors.
1.2 Introduction
The TLV320AIC11xxEVM-K 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 Microsoft Windows
®
XP operating systems only. Provisions are made for connecting all
audio inputs and outputs either from the modular connectors or with on-board terminals and external
microphone jack. An on-board electret microphone is also provided.
2 Analog Interface
For maximum flexibility, the TLV320AIC11xxEVM 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. These headers/sockets provide access to the analog input
and output pins of the device. Consult Samtec at www.samtec.com or call 1-800-SAMTEC-9 for a variety
of mating connector options. Table 1 summarizes the analog interface pinout for the TLV320AIC11xxEVM.
