MAX9867 Evaluation Kit
19-5085; Rev 1; 7/16
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 I2S-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 WindowsM 2000-, Windows XPM-,
and Windows VistaM-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.

MAX9867 Evaluation Kit
Quick Start
Recommended Equipment
MAX9867 EV kit (USB A-to-mini-B cable included)
User-supplied Windows 7 or Windows 8 PC with a
spare USB port
Pair of headphones (16I or greater)
Two single-ended analog audio sources
Digital audio equipment with two TOSLINK optical
cables
Refer to the MAX9867 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.
Procedure
The MAX9867 EV kit is fully assembled and tested.
Follow the steps below to verify board operation before
exercising the full features of the MAX9867:
1) Verify that all the jumpers are set in their default
positions, as shown in Table 1.
2) Connect one TOSLINK optical cable between the
digital audio equipment input and the J5 module on
the EV kit board.
3) Connect the other TOSLINK optical cable between
the digital audio equipment output and the J6 mod-
ule on the EV kit board.
4) 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.
5) 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 microphone input.
6) Connect one analog audio source to the J1 RCA
jack on the EV kit board.
7) Connect the other analog audio source to the J2
RCA jack on the EV kit board.
8) Connect the headphone to the J4 headphone jack
on the EV kit board.
9) Set the digital audio equipment audio output and
input sampling frequency to 48kHz.
10) Enable the digital audio equipment input and output.
11) Enable the analog audio sources.
12) Visit www.maximintegrated.com/evkitsoftware to
download the latest version of the EV kit software,
MAX9867EVSwSetupVx.x.ZIP.
13) Install the MAX9867 evaluation software on your com-
puter by running the MAX9867EVSwSetupVx.x.exe
program. The program files are copied and icons
are created in the Windows Start menu.
14) 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.
15) 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\Maxim Integrated\MAX9867
(default installation directory) using the Browse but-
ton. During device driver installation, Windows may
show a warning message indicating that the device
driver Maxim uses does not contain a digital signa-
ture. 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.
16) Start the MAX9867 EV kit software by opening its
icon in the Start | Programs | Maxim Integrated |
MAX9867 menu.
17) The EV kit software main window appears, as shown
in Figure 1. Verify that the message MAX9867:
Connected is displayed on the status bar at the bot-
tom of the software’s main window.
18) In the Clock Configuration group box, press the
Configure button.
19) In the MCLK Sources group box, click on the
Recovered Master Clock radio button.
20) Click on the DAC and Headphone Outputs tab.
In the Headphone Output Mode drop-down list,
select Stereo OCL.
21) Click on the Mic and Line Inputs tab. In the Line
Inputs group box, check the Enable Left Line In,
Enable Right Line In, Mute Left Line In, and Mute
Right Line In checkboxes. Muting the input does
not prevent the input from routing to the ADCs.
22) Click on the Filters tab. In the Codec Filtering
Mode drop-down list, select Audio (FIR).

23) On the top-right corner of the software’s main win-
dow, select Enabled from the drop-down list.
24) Verify that audio from the digital audio equipment
is output at the headphone and the analog audio
sources are output to the digital audio equipment.
Detailed Description of Software
Software Main Window
On the top of the main window, press the Read All but-
ton to read all the MAX9867 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 allows
a user to enable or disable the MAX9867.
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 eight tabs.
On each tab sheet, the user can exercise a group of
related configurations and check the register values.
Each control on the GUI generates the expected read
and/or write operations on the internal registers of the
MAX9867 and the CS8427 digital audio transceiver.

Detailed Description of Hardware
The MAX9867 EV kit is a complete digital audio evalu-
ation system for the MAX9867 low-power, stereo audio
codec. The EV kit provides translation between the
digital audio signals and optical S/PDIF signals to allow
easy connection with consumer electronics devices. See
Table 1 for a description of all EV kit jumper configura-
tions.
Clocking
On-Board Clock
The EV kit has one 12.288MHz and one 13MHz clock
oscillator on the board to provide flexible master-clock
selections for the MAX9867.
Recovered Clock
When the S/PDIF IN has a digital audio input and the
S/PDIF transceiver is in operation, the recovered clock
from the S/PDIF transceiver can be used as the master
clock for the MAX9867.
External Clocks
Connect an external clock source to jumper JU12 pin 2
to drive the MAX9867 MCLK pin without using the on-
board oscillator. The user must type in the correct clock
frequency in the MCLK Frequency edit box.
Jack Detection and
DC-Voltage Measurement
The MAX9867 has a JACKSNS/AUX pin that can be con-
figured to either detect the presence/absence of a jack
or accurately measure a DC voltage.
To measure a DC voltage, place a shunt on jumper JU7
and apply the DC voltage on the AUX pad. The on-board
resistor network (R5, R6) can be used to adjust the input
voltage ranges.
To detect the presence or absence of a jack, remove the
shunt on jumper JU7 and connect the JACKSNS pad to
a proper jack pin. Refer to the MAX9867 IC data sheet
for the details of jack-detection functionality.
Microphone Inputs
The MAX9867 features stereo differential microphone
inputs that can be connected to either analog or digital
microphones.
MICRP and MICRN pins can only connect to an analog
microphone. Place shunts on jumpers JU1 and JU3 to
use the MAX9867 MICBIAS for microphone biasing.
Place a shunt on jumper JU2 to connect MICRN to GND
for single-ended microphone input.
MICLP/DIGMICDATA and MICLN/DIGMICCLK pins can
connect either to an analog microphone or a digital
microphone, but not at the same time. For analog
microphone input, remove the shunts on jumpers JU8
and JU9. Place shunts on jumpers JU4 and JU6 to use
the MAX9867 MICBIAS for microphone biasing. Place
a shunt on jumper JU2 to connect MICLN to GND for
single-ended microphone input. For digital microphone
input, place shunts on JU8 and JU9 and remove con-
nections on the MICLP and MICLN pads. There are two
digital microphones on the EV kit board.
Headphone Outputs
There are two headphone jacks on the EV kit board.
Use J4 for differential or capacitorless output configura-
tion. Remove the shunts on jumpers JU10 and JU11.
Use J5 for single-ended output configuration. Remove
the shunts on jumpers JU10 and JU11 for fast turn-on
mode. Place the shunts on JU10 and JU11 for clickless
mode.
