A New Hardware Found window pops up when installing the USB driver for the first time. If you do not see a window that is similar to the one described above after 30 seconds, remove the USB cable from the board and reconnect it. Administrator privileges are required to install the USB device driver on Windows. 16) Follow the directions of the Add New Hardware Wizard to install the USB device driver. Choose the Search for the best driver for your device option. Specify the location of the device driver to be C:\Program Files\MAX9675 (default installation directory) using the Browse button. During device driver installation, Windows may show a warning message indicating that the device driver Maxim uses does not contain a digital signature. This is not an error condition and it is safe to proceed with installation. Refer to the USB_Driver_Help.PDF document included with the software for additional information. 17) Start the MAX9675 EV kit software by opening its icon in the Start | Programs menu. The EV kit software main window appears, as shown in Figure 1. 18) Check the Output Enable checkbox in the Individual Output Setting group box. 19) Press the Program button. 20) On the video measurement equipment, verify that the output signal matches the input signal.

Evaluates: MAX9675 MAX9675 Evaluation Kit Figure 1. MAX9675 EV Kit Software Main Window (Individual Output Address Mode) Detailed Description of Software The MAX9675 EV kit software main window shown in Figure 1 contains a device Address drop-down list, an Output Settings group box, an Address Recognition group box, and a device Reset button. Device Address Select the appropriate device address in the Address drop-down list according to the jumper settings on JU1-JU4. Jumpers JU1-JU4 configure the logic levels on the address pins of the MAX9675. Output Settings The Output Settings group box has all of the functions to configure the outputs of the MAX9675. In the Mode group box, click on the Mode 0 radio button to select the individual output address mode. Click on the Mode 1 radio button to select the complete matrix mode. In the individual output address mode, only one output is configured at a time. In the complete matrix mode, all outputs are configured in one SPITM command. When the Mode 0 radio button is selected, use the Individual Output Setting group box to configure an output. In the Individual Output Setting group box, use the Output Ch drop-down list to select the target output channel. Use the Input Ch drop-down list to select the input channel. A 1V/V or 2V/V gain can be set by the Gain drop-down list. Check the Output Enable checkbox to enable the selected output channel. After the Individual Output Setting group box is configured, press the Program button to send the SPI command to the MAX9675. The UPDATE pin of the MAX9675 will also be pulled low to transfer data from the mode registers to the switch matrix in the MAX9675.

MAX9675 EV Kit Software Main Window (Complete Matrix Mode) When the Mode 1 radio button is selected, as shown in Figure 2, the Individual Output Setting group box becomes the Output 0 group box, which is used to configure output channel 0. All other output group boxes are used to configure their corresponding output channels. Use the Input Ch drop-down list to select the input channel for the corresponding output channel. Check the appropriate Output Enable checkbox to enable the corresponding output channel. A 1V/V or 2V/V gain can be set using the Gain drop-down list. After all of the output group boxes are configured, press the Program button to send the 96-bit SPI command to the MAX9675. The UPDATE pin of the MAX9675 will be pulled low to transfer data from the mode registers to the switch matrix in the MAX9675. After the Program button is pressed and the SPI command is sent to the MAX9675, and if the device address in the Address drop-down list is correct, the address recognition output (AOUT) will assert low. In addition, the AOUT Asserted label in the Address Recognition group box will appear. Press the Reset button to pull the RESET pin of the MAX9675 low to reset the device. Detailed Description of Hardware The MAX9675 is a nonblocking 16 x 16 video crosspoint switch with buffered inputs and outputs. The MAX9675 EV kit has BNC connectors for all of the inputs and outputs. _______________________________________________________________________________________ 5 Evaluates: MAX9675 MAX9675 Evaluation Kit User-Supplied SPI Interface To use the MAX9675 EV kit with a user-supplied SPI interface, move the shunts of JU6-JU13 to the 2-3 position. Connect the user-supplied SPI signals to the appropriate pins on J16. See Table 2 for the pin description of header J16. Device Address JU1-JU4 set the logic levels of the address programming input pins A0-A3, respectively. Place the shunt in the 1-2 position to drive the corresponding address programming input pin high. Place the shunt in the 2-3 position to drive the corresponding address programming input pin low. 6 Table 2.
