General Description
Features
o USB Connectivity
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 trans-
mits 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 periph-

Detailed Description of Software
Evluates:7/MAX9258
The MAX9257/MAX9258 EV kit software contains four
tab sheets: ECU Control, Deserializer MAX9258,
Serializer MAX9257, and Camera Control.
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.
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.
Four registers on each of the MAX9258 and MAX9257
should have the same values. They should be config-
ured simultaneously for the SerDes pair to work proper-
ly. Check the Write Both 9258&9257 checkbox to
enable the write operation of the two devices on the
same control channel.
ECU Control Tab
The ECU Control tab sheet (Figure 3) lets the ECU con-
figure 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.
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.
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

On the bottom-left side of the software window, press
the Reset MAX9257 GUI button to set all the GUI val-
ues to the MAX9257 power-on-reset values. No opera-
tions are executed on the actual MAX9257 device. The
other four buttons: Read MAX9258 & 9257, Write
MAX9258 & 9257, Read MAX9257, and Write
MAX9257 let the user read or write to the MAX9258 and
the MAX9257 simultaneously or individually.
Serializer MAX9257 Tab
On the Serializer MAX9257 tab sheet (Figure 5), the
ECU can write or read all registers on the MAX9257 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 MAX9257 and the
MAX9258 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.
Camera Control Tab
On the Camera Control tab sheet (Figure 6), the ECU
can communicate to the emulated camera during a
control-channel session.

actions between the ECU and the camera.
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.
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 I2C interface. See the
Configuration Examples section for details.
By default, PCLK_IN is 30MHz, HSYNC_IN is 30kHz,
and VSYNC_IN is 60Hz. The duty cycles of all the sig-
nals are fixed at 50ꢀ.
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.
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

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 trans-
mission begins. The following procedure is an example
of one of many possible configurations:

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).
12) Use an oscilloscope to check that CCEN is toggling

again when the next control channel is available.
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.
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 syn-
chronization clock, and the vertical synchronization
clock. The frequencies are displayed in the
Onboard PCLK_IN, HSYNC_IN, VSYNC_IN Status
group box.
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.

15) Exercise different pixel clocks by selecting different
options in the Change PCLK_IN/HSYNC_IN/

should be in the range of the configured PRATE
range, and the following relationship formula must
be met:
4) Keep the four Write Both 9258&9257 checkboxes

7) Follow the reminder message by moving the shunts
from JU26 and JU27 (pins 1-2) to pins 2-3. Press
the OK button.
It is preferred to select the pixel clock frequency
before the clock is enabled.
16) To select a different UART speed, change the cam-
era UART speed first and then go to the ECU
Control tab sheet to change ECU UART speed
8) Now the camera and the SerDes use an I2C inter-
face. Navigate to any tab sheet and exercise the
features of the SerDes.
9) The I2C interface on the emulated camera can oper-
ate 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.
accordingly. Ensure that t
and t
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).
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.
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.

Figure 7a shows the schematic for the MAX9258.
Figure 7b shows the schematic for the power supplies,
a clock generator, and a microcontroller that communi-
cates with the PC. The microcontroller, together with an
FPGA, emulates an ECU.

I C Mode
If the camera uses an I2C interface, both the MAX9257
and MAX9258 should be configured to use the I2C
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:
Figure 7c shows the FPGA, which implements a high-
speed 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.
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.
Figure 7f shows the FPGA, which implements a high-
speed 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.
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.

DI2CS Core
Description of IP Cores
(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/micro-
controller. The DI2CS core supports all of the transmis-
sion 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
email Digital Core Design at info@dcd.pl for more infor-
mation.
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 info@dcd.pl for more information.
