S On-Board Digital Audio Interface Transceiver

S On-Board Fiber Optic Transmitter and Receiver

Modules

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.

S Isolation Header for Direct Communication with

the MAX9867 I²C and Digital Audio Interfaces

S Proven PCB Layout

download the latest version of the EV kit software,

MAX9867EVSwSetupVx.x.ZIP.

Quick Start

Recommended Equipment

MAX9867 EV kit (USB A-to-mini-B cable included)

•

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.

User-supplied Windows 7 or Windows 8 PC with a

spare USB port

•

Pair of headphones (16I or greater)

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.

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.

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.

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.

16) Start the MAX9867 EV kit software by opening its

icon in the Start | Programs | Maxim Integrated |

MAX9867 menu.

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.

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.

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.

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.

6) Connect one analog audio source to the J1 RCA

jack on the EV kit board.

20) Click on the DAC and Headphone Outputs tab.

In the Headphone Output Mode drop-down list,

select Stereo OCL.

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.

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.

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.

22) Click on the Filters tab. In the Codec Filtering

Mode drop-down list, select Audio (FIR).

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.

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.

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.

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.

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.

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.

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.

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.

Headphone Outputs

There are two headphone jacks on the EV kit board.

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.

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.

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.
