MAX9257/MAX9258 Evaluation Kit
The MAX9257/MAX9258 evaluation kit (EV kit) consists
of a MAX9257/MAX9258 evaluation board and software.
The MAX9257/MAX9258 EV kit is a fully assembled and
tested PCB that evaluates the MAX9257 serializer and
the MAX9258 deserializer (SerDes). The EV kit also
emulates an electronic control unit (ECU) and a camera.
The MAX9258 receives programming instructions from
the emulated ECU during the control channel and transmits to the MAX9257 over the serial video link. The
instructions can program or update the MAX9258,
MAX9257, or an external peripheral device such as a
camera. The MAX9257 communicates with the peripheral device with either an I2C or UART interface.
The MAX9257/MAX9258 EV kit includes Windows ®
2000/XP- and Windows Vista®-compatible software that
provides a simple graphical user interface (GUI) for
exercising the features of the MAX9257 and MAX9258.
The EV kit is connected to a PC through USB.

Detailed Description of Software
The MAX9257/MAX9258 EV kit software contains four
tab sheets: ECU Control, Deserializer MAX9258,
Serializer MAX9257, and Camera Control.
Warning: When the MAX9257/MAX9258 UART baud
rate ranges are changed, they do not take effect until
the next control channel is entered. The ECU baud rate
should not be changed during the current control
channel.
ECU Control Tab
The ECU Control tab sheet (Figure 3) lets the ECU configure the MAX9258, MAX9257, and the camera.
The ECU UART baud rate can be selected by choosing
the appropriate baud rate in the Select ECU UART
Baud Rate drop-down list. By default, the UART speed
is 400kbps. In base mode, the UART baud rate should
not be higher than 4.25Mbps.
Except for the menu-driven commands that can be
generated on the Deserializer MAX9258, Serializer
MAX9257, and Camera Control tab sheets, the ECU
commands can be written by typing commands in the
4
ECU Writes N Bytes to MAX9257/58/Camera edit box.
Similarly, the ECU commands can be read by typing
commands in the ECU Reads N Bytes from
MAX9257/58/Camera edit box. The write or read commands are not executed until the corresponding Write
or Read button is pressed. Follow the instructions displayed on the software GUI.
When the EV kit is powered up the first time, and the
MAX9257 is configured to be powered up remotely by
the ECU (REM is high), press the ECU Wakes Up
MAX9257 button to wake up the MAX9257. Refer to the
Remote Power-Up of the MAX9257 (REM = Pulled Up
to V CC ) section in the MAX9257/MAX9258 IC data
sheet for timing requirements of the remote wake-up.
Check the Prefix a SYNC frame everytime a
read/write command is sent checkbox when a SYNC
frame is desired before sending a command to the
MAX9258, MAX9257, or the camera. A SYNC frame is
needed only once every control channel.
Check the Postfix an END frame everytime a read/write
command is sent checkbox when an END frame is
desired after sending a command to the MAX9258,
MAX9257, or the camera. Do not send END frame after a
READ command. In a real application, the ECU can send
END frame after the READ operation is completed.
Press the Reset the EVKIT button to reset the EV kit
software and hardware. The user must manually disconnect and reconnect the power supply to reset the
EV kit hardware.
Deserializer MAX9258 Tab
On the Deserializer MAX9258 tab sheet (Figure 4), the
ECU can write or read all registers on the MAX9258 by
pressing the Write or Read buttons on the right of each
register. Refer to the MAX9257/MAX9258 IC data sheet
for the definition of each register.
Four registers on each of the MAX9258 and MAX9257
should have the same values. They should be configured simultaneously for the SerDes pair to work properly. Check the Write Both 9258&9257 checkbox to
enable the write operation of the two devices on the
same control channel.
On the bottom-left side of the software window, press
the Reset MAX9258 GUI button to set all of the GUI
values to the MAX9258 power-on-reset values. No
operations are executed on the actual MAX9258
device. The other four buttons: Read MAX9258 & 9257,
Write MAX9258 & 9257, Read MAX9258, and Write
MAX9258 let the user read or write to the MAX9258 and
the MAX9257 simultaneously or individually.

Figure 4. MAX9257/MAX9258 Evaluation Kit Software—Deserializer MAX9258 Tab
By default, the MAX9258, MAX9257, and the emulated
camera use the UART interface (JU26 and JU27 shunts
are set across pins 1-2). Press the Turn On D4, Turn
Off D4, Fast Blink D4, and Slow Blink D4 buttons to
demonstrate several simple communication transactions between the ECU and the camera.
A user can change the UART speed, enable/disable
the video clocks (PCLK_IN, HSYNC_IN, and
VSYNC_IN), select different video clock speeds, and
switch the camera to the I 2 C interface. See the
Configuration Examples section for details.
The MAX9257/MAX9258 EV kit can generate PCLK_IN,
HSYNC_IN, and VSYNC_IN signals with the following
relationships: HSYNC_IN = PCLK_IN/1000 and
VSYNC_IN = PCLK_IN/500000. By default they are not
6
enabled, so that an external pattern generator or piece
of video equipment can be connected to J6. If the
Enable PCLK_IN/HSYNC_IN/VSYNC_IN button is
pressed, the signals are enabled and the status of
these three signals are displayed in the Onboard
PCLK_IN, HSYNC_IN, VSYNC_IN Status group box.
By default, PCLK_IN is 30MHz, HSYNC_IN is 30kHz,
and VSYNC_IN is 60Hz. The duty cycles of all the signals are fixed at 50%.
Configuration Examples
This section describes how to configure the SerDes to
work in UART Never Come Back Operation, UART
With Finite CTO Operation, and I2C Mode. Use an
oscilloscope to monitor the activity on the MAX9258 TX,
RX, and CCEN pins.

Figure 5. MAX9257/MAX9258 Evaluation Kit Software—Serializer MAX9257 Tab
UART Never Come Back Operation
This operation is used in an application when the
ECU completes the configuration of the MAX9257/
MAX9258 right after power-up and does not want to
access the MAX9257/MAX9258 once the video transmission begins. The following procedure is an example
of one of many possible configurations:
1) Start the program or press the Reset the EVKIT
button on the ECU Control tab sheet (Figure 3).
2) If MAX9257 REM is set to high (JU25 shunt is set
across pins 1-2), press the ECU Wakes Up
MAX9257 button on the ECU Control tab sheet. If
MAX9257 REM is set to low (JU25 shunt is set
across pins 2-3), skip this step.
3) Navigate to the Deserializer MAX9258 tab sheet
(Figure 4). Press the Read MAX9258 & 9257 button
to refresh the current register values on the GUI.
4) Keep the four Write Both 9258&9257 checkboxes
checked.
5) Set t STO and t ETO on both the MAX9258 and
MAX9257 to expected values. Note that the tSTO
and t ETO times are based on the pixel clock
(PCLK_IN) time. For example, if PCLK_IN is 30MHz,
set STODIV to 1024 and STOCNT to 0, t STO =
(1024 x 1/30)µs ≈ 34µs. Set ETODIV to 1024 and
ETOCNT to 4, tETO = (1024 x 5/30)µs ≈ 170µs.
6) Set other MAX9258 registers as desired.

MAX9257/MAX9258 Evaluation Kit
Figure 6. MAX9257/MAX9258 Evaluation Kit Software—Camera Control Tab
7) Navigate to the Serializer MAX9257 tab sheet
(Figure 5). Select Enable in the SEREN drop-down
list within the Reg04 controls if it is not enabled.
8) Select Enable in the INTEN drop-down list within
the REG08 controls of the Serializer MAX9257 tab
sheet. INTEN is changed in both MAX9258 and
MAX9257 when the INTEN drop-down list is
changed on either tab sheet.
9) From this step on, the MAX9257 and the MAX9258
registers are no longer accessible. The ECU can
only communicate with the camera in bypass mode
because CTO is set to 0 (never come back).
10) Navigate to the Camera Control tab sheet (Figure
6). Press the Turn On D4, Turn Off D4, Fast Blink
D4, and Slow Blink D4 buttons, respectively, to ver8
ify that the ECU is communicating to the camera
properly.
11) Press the Enable PCLK_IN/HSYNC_IN/VSYNC_IN
button to enable the pixel clock, the horizontal synchronization clock, and the vertical synchronization
clock. The frequencies are displayed in the
Onboard PCLK_IN, HSYNC_IN, VSYNC_IN Status
group box.
12) Use an oscilloscope to check that CCEN is toggling
and the D1 green LED is lit up (MAX9258 LOCK pin
is asserted high).
13) Exercise different pixel clocks by selecting different
options in the Change PCLK_IN/HSYNC_IN/
VSYNC_IN group box. The selected pixel clock
should be in the range of the configured PRATE
_______________________________________________________________________________________
MAX9257/MAX9258 Evaluation Kit
Serial Word Length x Pixel Clock = Serial
Data Rate ≤ 840Mbps
It is preferred to select the pixel clock frequency
before the clock is enabled.
14) To select a different UART speed, change the camera UART speed first and then go to the ECU
Control tab sheet to change the ECU UART speed
accordingly. Ensure that tSTO and tETO values are
set correctly in order for the UART speed to work
properly. The MAX9258 REG07 FAST bit and
MAX9257 REG08 FAST bit should be configured
correctly before going to the never come back
operation.
15) Press the Disable PCLK_IN/HSYNC_IN/VSYNC_IN
button to disable the video clock inputs to the
MAX9257. Check that the D1 green LED is turned
off (MAX9258 LOCK pin stays low) and that the
control channel is available indefinitely (MAX9258
CCEN pin stays high).
16) Press the Enable PCLK_IN/HSYNC_IN/VSYNC_IN
button again to enable the video clock inputs to the
MAX9257. Check that the D1 green LED lights up
again.
UART with Finite CTO Operation
If tCTO < tETO then the MAX9257 and the MAX9258
registers can be accessed and UART communication
with the camera in bypass mode is possible.
1) Start the program or press the Reset the EVKIT
button on the ECU Control tab sheet (Figure 3).
2) If MAX9257 REM is set to high (JU25 shunt is set
across pins 1-2), then press the ECU Wakes Up
MAX9257 button on the ECU Control tab sheet. If
MAX9257 REM is set to low (JU25 shunt is set
across pins 2-3), then skip this step.
3) Navigate to the Deserializer MAX9258 tab sheet
(Figure 4). Press the Read MAX9258 & 9257 button
to refresh the current register values on the GUI.
4) Keep the four Write Both 9258&9257 checkboxes
checked.
5) Set t STO and t ETO on both the MAX9258 and
MAX9257 to desired values. Note that the tSTO and
t ETO times are based on pixel clock (PCLK_IN)
time. For example, if PCLK_IN is 30MHz, set
STODIV to 1024 and STOCNT to 0, tSTO = (1024 x
1/30)µs ≈ 34µs. Set ETODIV to 1024 and ETOCNT
to 9, tETO = (1024 x 10/30)µs ≈ 340µs.
6) Set t CTO on both MAX9258 and MAX9257 to
desired values. Note that the tCTO time is based on
the UART bit time. For example, if the UART speed
is 400kbps, set CTO to 64, tCTO = (64 x 2.5)µs =
140 µs.
7) Set other MAX9258 registers as desired.
8) Navigate to the Serializer MAX9257 tab sheet
(Figure 5). Select enable in the SEREN drop-down
list within the Reg04 controls if it is not enabled.
9) Select enable in the INTEN drop-down list within the
Reg08 controls on the Serializer MAX9257 tab
sheet. INTEN is changed in both MAX9258 and
MAX9257 when the INTEN drop-down list is
changed on either tab sheet.
10) Press the Read button to read back the contents of
Reg08. Ensure that the INTEN drop-down list displays disabled because CTO expired by the time
the read operation executed and STO/ETO are not
counting yet since the pixel clock is not activated.
11) Navigate to the Camera Control tab sheet (Figure
6). On this tab sheet, all ECU commands to the
camera follow this order in one control-channel session:
a) SYNC frame
b) Set MAX9258 INTEN to 1
c) Wait for 15 UART bit times
d) Set MAX9257 INTEN to 1
e) ECU command to the camera
After every command, CTO expires first because of
tCTO < tETO. This resets INTEN on both MAX9258
and MAX9257 to 0 so that they become accessible
again when the next control channel is available.
12) Press the Turn On D4, Turn Off D4, Fast Blink D4,
and Slow Blink D4 buttons to verify that the ECU
communicates to the camera properly.
13) Press the Enable PCLK_IN/HSYNC_IN/VSYNC_IN
button to enable the pixel clock, the horizontal synchronization clock, and the vertical synchronization
clock. The frequencies are displayed in the
Onboard PCLK_IN, HSYNC_IN, VSYNC_IN Status
group box.
14) Use an oscilloscope to check that CCEN is toggling
and the D1 green LED is lit (MAX9258 LOCK pin is
asserted high).

range, and the following relationship formula must
be met:
Evaluates: MAX9257/MAX9258
MAX9257/MAX9258 Evaluation Kit
15) Exercise different pixel clocks by selecting different
options in the Change PCLK_IN/HSYNC_IN/
VSYNC_IN group box. The selected pixel clock
should be in the range of the configured PRATE
range, and the following relationship formula must
be met:
Serial Word Length x Pixel Clock = Serial
Data Rate ≤ 840Mbps
It is preferred to select the pixel clock frequency
before the clock is enabled.
16) To select a different UART speed, change the camera UART speed first and then go to the ECU
Control tab sheet to change ECU UART speed
accordingly. Ensure that tSTO and tETO values are
set correctly in order for the UART speed to work
properly. The MAX9258 REG07 FAST bit and
MAX9257 REG08 FAST bit should be configured
correctly before choosing a different UART speed.
17) Press the Disable PCLK_IN/HSYNC_IN/VSYNC_IN
button to disable the video clock inputs to the
MAX9257. Check that the D1 green LED is turned
off (MAX9258 LOCK pin stays low) and that the
control channel is available indefinitely (MAX9258
CCEN pin stays high).
18) During any step above, the user can navigate to the
Deserializer MAX9258 or Serializer MAX9257 tab
sheets and perform read or write operations
because INTEN is reset to 0 after every operation.
I2C Mode
If the camera uses an I2C interface, both the MAX9257
and MAX9258 should be configured to use the I 2C
interface. Because the on-board emulated camera uses
the default UART interface, the camera must first be
switched from the UART interface to an I2C interface.
Follow the steps below to evaluate the SerDes link in
base mode when the I2C interface is enabled:
1) Start the program or press the Reset the EVKIT
button on the ECU Control tab sheet (Figure 3).
2) If MAX9257 REM is set to high (JU25 shunt is set
across pins 1-2), then press the ECU Wakes Up
MAX9257 button on the ECU Control tab sheet. If
MAX9257 REM is set to low (JU25 shunt is set
across pins 2-3), then skip this step.
3) Navigate to the Deserializer MAX9258 tab sheet
(Figure 4). Press the Read MAX9258 & 9257 button
to refresh the current register values on the GUI.
10
4) Keep the four Write Both 9258&9257 checkboxes
checked.
5) Set tCTO on both the MAX9257 and MAX9258 to 64.
6) Navigate to the Camera Control tab sheet (Figure
6) and press the Exit UART Mode => Enter I2C
Mode button (this button is available only when
CTO is not equal to 0).
7) Follow the reminder message by moving the shunts
from JU26 and JU27 (pins 1-2) to pins 2-3. Press
the OK button.
8) Now the camera and the SerDes use an I2C interface. Navigate to any tab sheet and exercise the
features of the SerDes.
9) The I2C interface on the emulated camera can operate at speeds up to 4.25MHz. This is the same as
the MAX9257 and MAX9258. Before changing the
ECU UART baud rate, the bit rates of the MAX9257
and MAX9258 must be configured properly.
Detailed Description of Hardware
The MAX9257/MAX9258 EV kit is a complete SerDes
pair evaluation system for the MAX9257 serializer and
MAX9258 deserializer. Check the schematic for
detailed EV kit hardware. The following is a brief
description of the EV kit design.
Deserializer Side
(Right Side of the EV Kit Board)
Figure 7a shows the schematic for the MAX9258.
Figure 7b shows the schematic for the power supplies,
a clock generator, and a microcontroller that communicates with the PC. The microcontroller, together with an
FPGA, emulates an ECU.
Figure 7c shows the FPGA, which implements a highspeed UART interface for the emulated ECU.
Serializer Side
(Left Side of the EV Kit Board)
Figure 7d shows the schematic for the MAX9257.
Figure 7e shows the schematic for the power supplies,
a clock generator, and a microcontroller that, together
with an FPGA, emulate a camera.
Figure 7f shows the FPGA, which implements a highspeed UART and a high-speed I2C interface for the
emulated camera. The FPGA also generates PCLK_IN,
HSYNC_IN, and VSYNC_IN for the emulated camera.
______________________________________________________________________________________
MAX9257/MAX9258 Evaluation Kit
The EV kit implements two digital cores on the FPGA
devices to generate high-speed UART signals and to
emulate a high-speed I2C slave device.
D16750 Core
(Provided by Digital Core Design)
The D16750 is an IP core of a universal asynchronous
receiver-transmitter (UART), functionally identical to the
TL16C750. Contact Digital Core Design for questions
relating to the D16750 IP core. See the Component
Suppliers section for contact information or email Digital
Core Design at [email protected] for more information.
DI2CS Core
(Provided by Digital Core Design)
The DI2CS is an IP core that provides an interface
between a microprocessor and an I2C bus. It can work
as a slave receiver or transmitter depending on the
working mode determined by a microprocessor/microcontroller. The DI2CS core supports all of the transmission modes required by the I2C specification (standard,
fast, and high speed). Contact Digital Core Design for
any questions relating to the DI2CS IP core. See the
Component Suppliers section for contact information or
