The MAX9851 evaluation system (MAX9851EVCMODU)
consists of a MAX9851 evaluation kit (EV kit), a companion
Maxim command module (CMODUSB) interface
board, and software. The MAX9851 EV kit is a fully
assembled and tested surface-mount printed-circuit
board (PCB) that evaluates the MAX9851 stereo audio
GSM/GPRS/EDGE CODEC with microphone inputs,
DirectDrive™ headphone amplifiers, receiver amplifier,
and stereo speaker amplifiers. 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 I²S-compatible signals. The EV kit provides RCA jacks
for connecting analog input signals and digital S/PDIF
signals. A 3.5mm headphone jack provides easy connection
of headphones to the PCB. The Maxim command
module interface board (CMODUSB) provides an
I²C interface through a PC serial or USB port. Windows®
98/2000/XP-compatible software, which can be downloaded
from the Maxim website, provides a user-friendly
interface to exercise the features of the MAX9851. The
program is menu driven and offers a graphical user interface
(GUI) with control buttons and a status display. The
MAX9851EVCMODU includes the EV kit and the
CMODUSB interface board. Order the MAX9851EVKIT if
no Maxim command module interface is needed.
