MAX9860 Evaluation Kit
General Description
The MAX9860 evaluation kit (EV kit) consists of a
MAX9860 evaluation board and software. The EV kit is
a fully assembled and tested circuit board that evalu-
ates the MAX9860 low-power, voiceband, mono 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 com-
municate using generic digital audio or I
2
S-compatible
signals. The EV kit provides fiber optic receiving and
transmitting modules for digital audio input and output.
The EV kit includes
2000-, Windows
M
-compatible software that provides a
and Windows Vista
graphical user interface (GUI) for exercising the features
of the MAX9860. The EV kit is connected to a PC through
a USB A-to-B cable.

Quick Start
• MAX9860 EV kit (USB A-to-B cable included)
8)
9)
Enable the digital audio equipment input and
output.
Enable the two analog audio sources.
Recommended Equipment
• User-supplied Windows 2000, Windows XP, or
Windows Vista PC with a spare USB port
• Speaker (16I or 32I, 50mW or greater)
• Two single-ended or differential analog audio
sources
• Digital audio equipment with two TOSLINK optical
cables
Refer to the MAX9860 IC data sheet while using this
EV kit for detailed descriptions of the codec’s features.
Note:
In the following sections, software-related items
are identified by bolding. Text in
bold
refers to items
directly from the EV kit software. Text in
bold and under-
lined
refers to items from the Windows operating system.
The MAX9860 EV kit is fully assembled and tested.
Follow the steps below to verify board operation before
exercising the full features of the MAX9860:
1)
2)
10) Visit
www.maxim-ic.com/evkitsoftware
to down-
load the latest version of the EV kit software,
9860Rxx.ZIP.
11) Install the MAX9860 evaluation software on your
computer by running the INSTALL.EXE program.
The program files are copied and icons are created
in the Windows
Start
menu.
12) Connect the USB cable from the PC to the EV kit
board. A
New Hardware Found
window pops up
when installing the USB driver for the first time.
If a window is not seen that is similar to the one
described above after 30s, remove the USB cable
from the board and reconnect it. Administrator privi-
leges are required to install the USB device driver
on Windows.
13) Follow the directions of the
Found New Hardware
window to install the USB device driver. Manually
specify the location of the device driver to be
C:\Program Files\MAX9860
(default installation
directory) using the
Browse
button. During device
driver installation, Windows may show a warning
message indicating that the device driver Maxim
uses does not contain a digital signature. This is
not an error condition and it is safe to proceed
with installation. Refer to the USB_Driver_Help.PDF
document included with the software for additional
information.
14) Start the EV kit software by opening its icon in the
Start | Programs
menu.
15) The EV kit software main window appears as shown
in Figure 1. Verify that the message
MAX9860:
Connected
is displayed on the status bar at the
bottom of the software’s main window.
16) In the
Clock Sources
group box, click on the
Recovered Master Clock
radio button.
17) Press the
Configure
button.
18) On the top-right corner of the software’s main win-
dow, select
Enabled
from the drop-down list.
19) Verify that audio from the digital audio equipment
is output at the speaker and the two analog audio
sources are output to the digital audio equipment.
Procedure
Verify that all of the jumpers are set in their default
positions, as shown in Table 1.
Connect one TOSLINK optical cable between the
digital audio equipment input and the J1 module on
the EV kit board.
Connect the other TOSLINK optical cable between
the digital audio equipment output and the J2 mod-
ule on the EV kit board.
Connect one analog audio source to the MICLP
and MICLN pads on the EV kit board. Connect the
MICLN pad to GND for single-ended microphone
input.
Connect the other analog audio source to the
MICRP and MICRN pads on the EV kit board.
Connect the MICRN to GND for single-ended micro-
phone input.
Connect the speaker to the OUTP and OUTN pads
on the EV kit board.
Set the digital audio equipment audio output and
input sampling frequency to 48kHz.

Detailed Description of Software
On the top of the main window, press the
Read All
button
to read all of the MAX9860 register values and update
the GUI. Press
Reset
to reset the EV kit hardware. Press
Connected
to set up the connection between the EV kit
and the software application. The drop-down list lets a
user enable or disable the MAX9860.
The
Device Status
group box reports the status of vari-
ous device functions. Check/uncheck the checkboxes to
enable/disable the hardware interrupts for each status
flag.
The lower side of the main window includes six tabs. On
each tab sheet, the user can exercise a group of related
configurations and check the register values. Each con-
trol on the GUI generates the expected read and/or write
operations on the internal registers of the MAX9860 and
the CS8427 digital audio transceiver.
Select the
Save Configuration
menu item to save the
current EV kit configuration to a text file that can be
loaded at a later time. Select
Load Configuration
to
reload settings from a saved file.
Select
Exit
to exit the application.
Select the
View Transceiver Registers
menu item to
display or hide the
CS8427
tab to change the digital
audio transceiver registers.
Select the
Power On Reset
menu item to reset the
MAX9860 to its power-on state. Select
Read Status
to
read the MAX9860 status registers. Select
Auto Read
Status
to enable the automatic read of the MAX9860 sta-
tus registers. Select
Auto Connect
to automatically set
up the connection between the EV kit and the software
application in case the connection is lost.
Select the
Reconnect to EVKIT
menu item to set up
the connection between the EV kit and the software
application.
Select
Debug Mode

Auto Read Status
menu item before using
the command module interface. The I
2
C dialog boxes
accept numeric data in binary, decimal, or hexadecimal.
Hexadecimal numbers should be prefixed by $ or 0x.
Binary numbers must be exactly eight digits. See Figure
2 for an example of this control method.
