The MAX9853 evaluation system (MAX9853EVCMODU) consists of a MAX9853 evaluation kit (EV kit), a companion Maxim command module (CMODUSB) interface board, and software. The MAX9853 EV kit is a fully assembled and tested surface-mount printed-circuit board (PCB) that evaluates the MAX9853 stereo audio GSM/GPRS/EDGE CODEC with microphone inputs, DirectDrive™ headphone amplifiers, receiver amplifier, and stereo line outputs. 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 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 MAX9853. The program is menu driven and offers a graphical user interface (GUI) with control buttons and a status display. The MAX9853EVCMODU includes the EV kit and the CMODUSB interface board. Order the MAX9853EVKIT if no Maxim command module interface is needed.
