MAX9264 Evaluation Kit
Evaluates: MAX9263/MAX9264
4.3) Connect the power supply (+) to VIN.
4.4) Connect the power supply (-) to GND.
5) Optional: Verify that the repeater passes power-on
self-test without TX_B1 and RX_D1.
5.1) Enable the 5V power supply.
5.2) The Board #2 UC_R firmware verifies that
required devices are attached and that required
input signals are present. With no TX_B1
connection, the UC_R firmware should light
LED127 and blink six red flashes on LED120 (to
repeat the power-on test, press and release the
reset button, SW122). If only four or five flashes
on LED120, then RX_R1 is not connected
correctly to TX_R1.
5.3) Disable the 5V power supply after verifying
UC_R reports the expected diagnostic code
(six flashes).
6) Connect the authorized display MAX9264 EV kit
RX_D1.
6.1) Configure Board #4 RX_D1 (MAX9264 EV kit) as
follows:
6.1.1) JU1 (CDS) = 2-3.
6.1.2) JU10 = open (Board #4 RX_D1 micro-
controller is not powered).
6.2) Connect the digital video display to Board #4,
header H1.
7) Connect the digital video source (or function genera-
tors) to Board #1 TX_B1 as follows:
7.1) Connect video data D[0:28] to header H1,
even-numbered pins 2–58.
7.2) Connect the ground return to header H1,
odd-numbered pins 1–71.
7.3) Connect vertical sync VSYNC to header H1, pin
40.
7.4) Connect PCLK_IN to header H1, pin 62.
8) Connect a Rosenberger cable between Board #1
TX_B1 and Board #2 RX_R1 connector J1.
9) Connect a Rosenberger cable between Board #3
TX_R1 and Board #4 RX_D1 connector J1.
10) Set JU2 (BWS) and JU4 (DRS) for all four boards to
the correct setting for the video signal PCLK frequen-
cy range. For example, if PCLK is between 8.33MHz
and 16.7MHz, set JU2 (BWS) = 2-3 and JU4 (DRS)
=1-2. Refer to the MAX9263/MAX9264 IC data sheet
for more details.
11) Enable the 5V power supply. Verify that Board #2
LED3 and LED4 are on. Verify that Board #3 LED120
is on. Verify that Board #4 LED3 and LED4 are on. No
LEDs on Board #1.
12) Enable PCLK. Verify that Board #2 LED3 and LED4
are on. Board #2 LED2 may or may not be visible
due to the reduced IOVDD voltage (the LED2 circuit
is designed for 3.3V, not 1.8V operation). Verify that
Board #4 LED2, LED3, and LED4 are on.
13) Enable the video source (or function generator
driving VSYNC).
14) The UC_R firmware performs a power-on self-test to
verify that RX_R1 and TX_R1 are both accessible.
The TX_B1-RX_R1 link is authenticated and then
the TX_R1-RX_D1 link is authenticated. Encryption
is enabled on both links. Finally, the KSV values are
compiled and the SHA hash vector V is compared.
The firmware reports success by lighting green
LED126. If any part of the process fails, the firmware
reports failure by lighting red LED127 while flashing
diagnostic LED120. Table 2 lists the diagnostic LED
codes for the repeater firmware (to repeat the power-
on test, press and release the reset button, SW122).
15) Optional: Use the EV kit software to verify link authen-
tication and encryption.
15.1) Install the EV kit software and USB driver on
your computer by running the INSTALL.EXE
program inside the temporary folder. The pro-
gram files are copied to your PC and icons
are created in the Windows Start | Programs
menu. During software installation, some ver-
sions of Windows may show a warning mes-
sage indicating that this software is from an
unknown publisher. This is not an error condi-
tion and it is safe to proceed with installation.
Administrator privileges are required to install
the USB device driver on Windows.
15.2) Start the MAX9264 EV kit software by opening
its icon in the Start | Programs menu. The EV
kit software configuration window appears, as
shown in Figure 8.
15.3) Press the Connect button and the configura-
tion window disappears. The software resets
the bulkhead firmware, which in turn resets the
repeater firmware. Authentication success is
indicated by green-light LED126, or failure is
indicated by red-light LED127.
15.4) The EV kit software main window appears, as
shown in Figure 1. When using the repeater
firmware, the EV kit software tries to read the
registers while the repeater firmware is busy
authenticating the display, so initially the Figure
1 window may show failed reads. This is not an
error.
15.5) Press the Read All button to read all regis-
ters on the MAX9263 (Board #1 TX_B1) and
MAX9264 (Board #2 RX_R1).
15.6) On the HDCP tab sheet (Figure 7), verify that
HDCP authentication between Board #1 and
Board #2 is successful. The corresponding
Bksv and Aksv values should match, and the Ri
keys should be updated with the same value.
15.7) Verify that HDCP authentication between Board
#3 and Board #4 is successful, by examin-
ing the KSV list (the software cannot directly
