Quick Start Recommended Equipment Before beginning, the following equipment is needed: • MAX9406 EV kit • A PC using Intel’s Eaglelake/Cantiga chipset with an integrated graphics controller • A built-in laptop LCD screen or an external monitor with a VGA interface as the primary display • Another LCD monitor with a DVI or HDMI interface as the secondary digital display Note: In the following sections, software-related items are identified by bolding. Text in bold refers to items directly from the EV kit software. Text in bold and underlined refers to items from the Windows® operating system. Procedure The MAX9406 EV kit is fully assembled and configured for HDMI output on J2. Follow the steps below to verify board operation: 1) Verify that all jumpers (J3–J11) are in their default positions, as shown in Table 1. 2) Check if the graphics driver and video BIOS are already installed by moving the mouse pointer (arrow) all the way down to the bottom of the primary display to show the task bar. Look at the notification area (system tray) at the right side of the task bar to find the Digital Display utility. If not found, the graphics driver and video BIOS need to be installed. 3) Carefully plug in the MAX9406 EV kit into an available PCIe bus slot. Connect an LCD monitor with an HDMI interface to the HDMI plug on the MAX9406 EV kit using an HDMI cable. Or, connect an LCD monitor with a DVI interface using a DVI-to-HDMI conversion cable. 4) The secondary monitor connected through the HDMI port will light up if the digital display is enabled. If no video appears, move the mouse pointer (arrow) all the way down to the bottom of the primary display to show the task bar. Further, move the mouse pointer to the notification area at the right side of the task bar and onto the Digital Display utility. Right click the Display Port and then select the Digital Display and Monitor option. The LCD monitor connected to the EV kit will light up. µMAX is a registered trademark of Maxim Integrated Products, Inc.

Highspeed channel data comes from the PCIe bus (J1), goes through the MAX9406, and outputs at the HDMI connector (J2). The MAX9406 is enabled by jumper J8. The MAX9406 also relays the hot-plug detection signal from the HDMI plug to the PCIe bus through an inverter (U5-D) when a shunt is placed across pins 2-3 of jumper J9. The hot-plug detection signal is amplitudelimited to 0.9V at the PCIe bus side. The 5V supply matching the HDMI interface side is converted down from the 12V supply of the PCIe bus by the MAX1659 (U2). Three MAX3208E chips (U4, U6, and U7) provide ESD protection for both high-speed and DDC channels on the HDMI interface. The AT24C02 EEPROM (U3) provides an EDID for testing purposes. The AT24C02 is initially un-programmed. Pullup resistors (1.5kΩ) are provided on both PCIe and HDMI sides of the DDC channel. Evaluating the MAX9406 DP-to-HDMI Dongle Board The MAX9406 EV kit can also be used to evaluate a MAX9406-based DP-to-HDMI level-shifter dongle board. To evaluate a dongle board, move resistors R28–R35 to locations R20–R27 to isolate the MAX9406 on the EV kit. Note: Connector U8 is mounted at assembly, but is not production tested. Table 1.
