MAX9867 Evaluation Kit

Evaluates: MAX9867

19-5085; Rev 0; 12/09

General Description

The MAX9867 evaluation kit (EV kit) consists of a

MAX9867 evaluation board and software. The EV kit is a

fully assembled and tested circuit board that evaluates

the MAX9867 low-power, stereo audio codec. The EV

kit is designed to send and receive digital audio data in

the Sony/Philips digital interface (S/PDIF) format and can

be optionally configured to communicate using generic

digital audio or I

S-compatible signals.

The EV kit provides two RCA jacks for analog audio input

signals and two 3.5mm headphone jacks for analog

audio output signals. The EV kit also provides fiber optic

receiving and transmitting modules for digital audio input

and output.

The EV kit includes Windows

2000-, Windows XP

and Windows Vista

-compatible software that provides a

graphical user interface (GUI) for exercising the features

of the MAX9867. The EV kit is connected to a PC through

a USB A-to-mini-B cable.
