Quick Start
Required Equipment
● MAX9276A/MAX9280A coax EV kit (USB cable
included)
● MAX9275/MAX9279 coax EV kit (USB cable
included)
● 2m Rosenberger FAKRA cable assembly (included
with the deserializer EV kit)
● Parallel data source (such as digital video)
● Optional: Function generator (needed only if parallel
data lacks a pixel clock)
● User-supplied Windows XP, Windows Vista, or
Windows 7 PC with a spare USB port (direct 500mA
connection required; do not use a bus-powered hub)
● 5V DC, 500mA power supply

Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1) Download and install the EV kit software from
www.maximintegrated.com/EVkitsoftware .
2) Install the appropriate USB driver for your PC from
the links provided.
3) Verify that all jumpers are in their default positions, as
shown in Table 1 .
4) With the power supply and function generator off,
connect the 5V power supply to the +5VIN terminal
pad on the serializer EV kit.
5) Connect the USB cable from the PC to the deserial-
izer EV kit (J10). A Windows message appears when
connecting the EV kit board to the PC for the first
time. Each version of Windows has a slightly different
message. If you see a Windows message stating
ready to use , then proceed to the next step; other-
wise, open the USB_Driver_Help_200.PDF to verify
that the USB driver was successfully installed.
6) Connect the FAKRA cable from the serializer EV kit
OUT+ connector to the deserializer EV kit IN+ con-
nector.
7) Connect the parallel data source to the serializer EV
kit headers (H1_DIN28:0).
8) Connect pixel clock or function generator to the serial-
izer EV kit header (H1_PCLK_IN).
9) Turn on power supply and function generator.
10) Verify that LED_PWR on the serializer EV kit turns on,
indicating that the board has power.
11) Verify that LED_D2 on the deserializer EV kit turns
on, indicating that the microcontroller is powered and
enabled.
12) Verify that LED_LOCK on the deserializer EV kit lights
up, indicating that the link has been successfully
established. If LED_LOCK is off or LED_ERROR is
on, double-check that the PCLK_IN signal is clocking
data.
13) Start the EV kit software by selecting Start | Pro-
grams | Maxim Integrated | MAXSerDesEV-D |
MAXSerDesEV-D . The Configuration Settings win-
dow will appear ( Figure 1 ). Jumper settings in this
window are for user reference and guide to properly
configure the evaluation board. Jumper settings do
not force the serializer or deserializer into a particular
mode of operation.
14) UART mode support: To configure for UART
mode, on the deserializer board, change jumpers
JU_I2CSEL from H to the L position. On the serializer
board, change jumpers JU_CONF1 and JU_CONF0
as shown in the Serializer group box, JU_TXSCL
from SCL to the TX position, and JU_RXSDA from
SDA to the RX position.
15) Press the Identify Devices button to have the GUI
scan the bus for possible listeners. In case no device
was identified, the most likely cause is improper jump -
er settings. Identify the problem before continuing.
16) Press the Connect button to launch the Evaluation
Kit window ( Figure 2 ).
17) Press the Read All button to read all registers on the
deserializer and serializer.
