Procedure

The MAX9260 EV kit is fully assembled and tested.

Follow the steps below to verify board operation:

1) Visit www.maxim-ic.com/evkitsoftware to down-

load the latest version of the EV kit software,

9259Rxx.ZIP. Save the EV kit software to a tempo-

rary folder and uncompress the ZIP file. (Note: the

MAX9260 EV kit uses the MAX9259 EV kit software.

The two boards are normally used together.)

9) Verify that MAX9259 EV kit LED120 lights up,

indicating that the microcontroller is powered and

enabled.

10) Verify that MAX9260 EV kit LED120 lights up,

indicating that the microcontroller is powered and

enabled.

2) Install the EV kit software on your computer by run-

ning the 9259Rxx.msi program inside the temporary

folder. The program files are copied and icons are

created in the Windows Start | Programs menu.

11) Verify that MAX9260 EV kit LED2 lights up, indicat-

ing that the link has been successfully established.

If LED2 is off or LED1 is on, double-check that

PCLK_IN signal is clocking data.

3) Verify that all jumpers are in their default positions,

as shown in Table 1.

12) Optional Audio Demo: Press and release switch

13) Start the MAX9259 EV kit software by opening its

icon in the Start | Programs menu. The EV kit soft-

ware configuration window appears, as shown in

Figure 7.

27) Toggle MAX9260 EV kit switch SW2 down. Verify

that MAX9259 EV kit LED1 turns off, indicating that

MAX9260 INT input is not asserted.

28) In the software’s MAX9260 tab, scroll to

that the INT checkbox is not checked, indicating

that MAX9260 INT input is not asserted.

14) Press the Connect button and the configuration

window disappears.

15) The EV kit software main window appears, as shown

in Figure 1.

Detailed Description of Software

16) Press the Read All button to read all registers on the

The main window of the evaluation software (Figure

1) shows a block diagram representing the MAX9259/

MAX9260 system. The left column shows MAX9259 input

data sources, and the right column shows MAX9260

output data sinks.

MAX9259 and MAX9260.

17) I C Slave Device Demo: Make sure MAX9260 EV kit

headers JU151–JU154 are in the 1-2 position.

18) In the software’s MAX7324 tab (Figure 4), press

the Search for MAX7324 button. Verify that the

MAX7324 Device Address drop-down list shows

0xDA (JU151=1-2 JU152=1-2).

The Change Configuration button (Figure 1) brings

up the Configuration window (Figure 7), allowing the

software GUI to select which side of the link the USB

cable should be plugged into. Controlling from the

MAX9260 side requires changing some jumper set-

tings as described in this window. If the MAX9259

and MAX9260 device addresses have been previously

changed from their factory power-on-reset values, the

new addresses must be specified in the Configuration

window to allow register access.

19) Press the LED151-LED158 ON button. Verify that

MAX9260 EV kit LED151–LED158 turn on.

20) Press the LEDs Alternating button. Verify that

MAX9260 EV kit LED151, LED153, LED156, and

LED158 turn off.

21) GPIO Demo: In the software’s MAX9260 tab (Figure

3), scroll down to Register 0x06. Uncheck the

GPIO1OUT checkbox and press the Write button.

Verify that MAX9260 EV kit LED4 turns off.

The Baud Rate drop-down list sets the communications

baud rate. The USB link uses the same baud rate as the

MAX9259/MAX9260. Note that the baud rate should only

be changed one step at a time.

22) Uncheck the GPIO0OUT checkbox and press

the Write button. Verify that MAX9260 EV kit LED3

turns off.

The Read All button reads all of the MAX9259 and

MAX9260 device registers. Reset to Default Values

restores recommended factory settings, and Write All

writes all MAX9259/MAX9260 device registers with the

values shown in the GUI.

23) Check the GPIO1OUT checkbox and press

the Write button. Verify that MAX9260 EV kit LED4

turns on.

24) Check the GPIO0OUT checkbox and press

the Write button. Verify that MAX9260 EV kit LED3

turns on.

The MAX9259 tab sheet (Figure 2) provides direct access

to all registers of the MAX9259, and the MAX9260 tab

sheet (Figure 3) provides direct access to all registers of

the MAX9260. Each register has its own Read and Write

button. The small circle next to the Read button turns yel-

low to indicate an attempt to read or write, red to indicate

a failed read or write, and green to indicate a successful

read or write operation.

25) INT Demo: Toggle MAX9260 EV kit switch SW2 up.

Verify that MAX9259 EV kit LED1 turns on, indicating

that MAX9260 INT input is asserted.

26) In the software’s MAX9260 tab, scroll to

that the INT checkbox is checked, indicating that

MAX9260 INT input is asserted.

The MAX7324 tab sheet (Figure 4) controls the I C I/O

expander on the remote side of the link. When USB is

plugged into the MAX9259 EV kit, the MAX7324 tab

sheet controls the MAX7324 (U15) on the MAX9260

_______________________________________________________________________________________

MAX9260 Evaluation Kit

EV kit. Note that the MAX7324 actually has two device

addresses; for simplicity, the software GUI only displays

the device address associated with MAX7324 outputs.

For details, refer to the MAX7324 IC data sheet.

Below header H1, the board layout has three sections:

microcontroller (U10–U14), I C slave device (U15), and

audio (U20–U25). The microcontroller and I C slave

device sections are identical on MAX9259 and MAX9260

EV kits.

The PRBS Test tab sheet (Figure 5) uses the MAX9260

registers to perform a pseudorandom bit sequence

(PRBS) error-rate test. Select the test duration (maxi-

mum 32767s = 9.1hrs) and press the Start button. The

software GUI configures the MAX9260 to begin the

PRBS test, counts down the specified delay time, and

then reports the final value of the MAX9260 PRBSERR

The audio section of the MAX9259 EV kit contains

S/PDIF-to-I S audio converter circuits (U20–U25), which

can be disabled by JU210 for applications already hav-

ing I S audio.

The audio section of the MAX9260 EV kit contains I S-

to-audio DAC circuits (U20, U21) and a Class D stereo

power amplifier (U25). The audio DAC circuits are similar

to the MAX9850 EV kit, and the power amplifier circuit is

similar to the MAX9701 EV kit.

The Interface History and Low Level Access tab

sheet (Figure 6) shows the recent low-level commu-

nications activity between the software GUI and the

MAX9259/MAX9260. The Register Access group box

provides arbitrary device read/write control, support-

ing additional user-supplied devices besides the on-

board MAX9259, MAX9260, and MAX7324. The Device

Address, Register, and Data drop-down lists specify

the device address and the register within the device, as

well as one optional byte of data to be written. Pressing

the Write Register button writes one byte of data to

the specified device register. Read Register reads the

specified device register and reports the results into the

Interface History window. Devices that are not register-

based (such as the MAX7324) are supported by Send

Data (no register) and Receive Data (no register).

User-supplied devices requiring other interface proto-

cols must use Raw TX byte codes to communicate.

Note that in bypass mode, raw data is passed to the

user-supplied slave device directly without modification.

User-Supplied Interface

To use the MAX9260 EV kit with a user-supplied inter-

face, first cut the PCB traces at jumpers JU141 and

JU142. Next, apply your own TX/SCL signal at the U1

side of JU141 and RX/SDA at the U1 side of JU142.

Refer to the MAX9259/MAX9260 IC data sheet for details

about UART protocol for base mode, write data format,

read data format, selecting base mode or bypass mode,

and selecting UART or I C slave device.

User-Supplied Power Supply

The MAX9250 and MAX9260 EV kits are powered com-

pletely from the USB port by default. The 5V USB bus

power is supplied to the remote EV kit over the link cable

by default. Jumper JU10 powers the link cable (VBUS)

from the 5V USB supply, and jumper JU11 connects the

link cable VBUS to the VIN power supply.

To provide external power to each EV kit’s VIN, and still

power both microcontrollers from USB, remove the shunt

from JU11, but leave the shunt at JU10 installed. The link

cable will carry the USB 5V bus power to the remote EV

kit board, but external user-supplied VIN supplies are

required to power the MAX9259 and the MAX9260.

Detailed Description of Hardware

The MAX9260 EV kit provides a proven layout for the

MAX9260. On-board level translators, I S stereo audio

DAC, Class D audio power amplifier, and easy-to-use

USB-PC connection are included on the EV kit.

To provide different power supplies to DVDD, AVDD, and

IOVDD, remove the shunts from jumpers JU21, JU22,

and JU23, and apply external user-supplied power at the

DVDD, AVDD, and IOVDD oval pads.

The MAX9260 EV kit board layout is divided into four

principal sections.

From header H1 to connector J1 are the support compo-

nents specific to the MAX9260. On-board LDO regulator

U2 powers the AVDD, DVDD, and IOVDD supplies from

VIN. Jumper JU11 optionally connects VIN to the link

cable, powering the remote EV kit board.

The I S audio link demonstration requires both MAX9259

EV kit and MAX9260 EV kit microcontrollers (U12) to be

powered, otherwise the on-board S/PDIF-to-I S con-

verter or the I S audio DAC does not initialize.

MAX9260 Evaluation Kit

MAX9259 EV kit software GUI. The following information

is provided for reference only.

Detailed Description of Firmware

The DS89C450 microcontroller (U12) runs custom firm-

ware, which ensures that no breaks occur within reg-

ister read/write commands. The firmware records 9-bit

even-parity data received from the USB interface while

RTS is set, and plays back the 9-bit data with 1.5 stop

bits timing when RTS is cleared. Data received from the

MAX9260 is relayed to USB immediately.

Firmware command “?” prints the firmware version ban-

ner message and brief command list.

Firmware command “B” changes the baud rate by

changing the internal TH1 baud-rate divisor. Refer to

firmware help command “?” for details. Pressing switch

SW122 resets the USB baud rate to 921600 baud. The

software GUI automatically sends the baud-rate change

command.

The audio chips are initialized by an I C command

sequence sent by the firmware when the microcon-

troller is reset. The same firmware runs on both the

MAX9259 and MAX9260 EV kit boards, so this initializa-

Firmware command “T” supports waking up the MAX9259

from the MAX9260 side of the link. Command “T” per-

forms a dummy read, followed by a delay on the order

of 1ms to 8ms, and finally writes a register value. For

example, send “T810558800483” to read from device

address 0x81 register 0x05, delay 4ms, then write to

device address 0x80 register 0x04 data 0x83. This is

the MAX9259 wake-up sequence for the default device

addresses. The software GUI automatically sends this

command when the Wake Up MAX9259 button is

pressed.

tion sequence covers both the S/PDIF-to-I S converter

and the MAX9850 I S stereo audio DAC. Pressing switch

SW122 resets the microcontroller, resending the audio

I C initialization commands.

The firmware also supports a small set of commands,

available when RTS is clear. Since all register read/

write requests are sent with RTS set, there is no conflict

between register data and firmware commands. These

firmware commands are issued automatically by the
