Procedure
1) Carefully connect the boards by aligning the two rightangle headers of the MAX4455 EV kit with the corresponding headers of the MAX4358 EV kit. Gently press them together. The two boards should be flush against one another. 2) With the power supply off, connect the power supply to the MAX4358 EV kit terminal block TB1 (see Table 1). 3) With the power supply off, connect the power supply to the MAX4455 EV kit terminal block TB1 (see Table 1). 4) Install the EV system software on your computer by running the INSTALL.EXE program on the CD-ROM. The program files are copied and icons are created for them in the Windows Start menu. Note: Windows 2000 requires an extra installation step; refer to file win2000.pdf. 5) Ensure that the MAX4358 jumpers JU1-JU4 are open. 6) Turn on the power supply. 7) Connect the 25-pin I/O extension cable between the computer's parallel port and the MAX4358 EV kit. The MAX4358 EV kit includes a suitable 25-pin I/O extension cable. Snap on the included ferrite bead to reduce PC-generated noise from affecting the video boards. 8) Start the program by opening its icon in the Start menu. 9) Connect video signal sources to IN00...IN03 on the MAX4358 EV kit. 10 Connect video displays to OUT00...OUT03 on the MAX4358 EV kit. 11) Confirm that the software successfully connected video source IN00 to video monitor OUT00. The video signal should be visible on the monitor.
Detailed Description of Software
The MAX4455 EV kit software is a simple but effective paint program that draws on the on-screen display memory. There are nine drawing windows: one for each of the eight on-screen display channels, and a master window for simultaneously writing multiple channels. The large blue area represents the on-screen display memory. Each pixel in this area corresponds to one pixel in the on-screen display memory. Transparent areas are blue. The OSDKEY signal is automatically generated for any pixel that is not transparent. The software implements a few simple tools for drawing lines, boxes, and text. User-generated graphics can be loaded from standard Windows bitmap files, and the contents of the on-screen display can be saved to a standard Windows bitmap file. Tables 2-10 describe the buttons found on various toolbars.

MAX4455 Evaluation Kit/Evaluation System
Loading and Saving Files
The MAX4455 on-screen display uses 15-level grayscale patterns. When the MAX4455 EV kit software saves an image as a windows bitmap, each pixel of the on-screen display image is converted from 15-level grayscale into an equivalent RGB value: osd_value &= 0x0F; if (osd_value == 0) { unsigned __int8 red = 0; unsigned __int8 green = 0; unsigned __int8 blue = 255; } else { unsigned __int8 greyscale_nybble = osd_value + 1; double luma = (greyscale_nybble * 256.0 / 16.0); if (luma > 255.0) { luma = 255.0; } if (luma < 0) { luma = 0; } unsigned __int8 red = luma; unsigned __int8 green = luma; unsigned __int8 blue = luma; } color =((blue * 0x10000) | (green * 0x100) | (red)); When the MAX4455 EV kit software loads a Windows bitmap image, each pixel of the image is converted from RGB into an equivalent brightness (luma) value, in accordance with the following equation: Luma = (0.299 x Red) + (0.587 x Green) + (0.114 x Blue) The MAX4455 EV kit software uses pure saturated blue (RGB value of red = 0, green = 0, blue = 255) to designate transparent pixels. Example code: converting RGB value into MAX4455 on-screen display control nybble: const double ar = 0.299, ag = 0.587, ab = 0.114, offset = 0; double luma = ar x red + ag x green + ab x blue + offset; unsigned __int8 greyscale_nybble = ((luma * 16.0) / 256) + 0.5; if (greyscale_nybble > 15+1) { greyscale_nybble = 15+1; } if (greyscale_nybble < 1+1) { greyscale_nybble = 1+1; } osd_control_value = greyscale_nyb ble - 1;
Creating Test Patterns
Simple brightness-gradient test patterns can be drawn interactively using the horizontal or vertical luma bar drawing tool. Click the desired tool button ( or ), and then drag the mouse across the opposite corners of the desired region. The white bar is always drawn near where the mouse is first clicked. All 15 grayscale levels are drawn, and one additional transparent bar is drawn just after the black bar. Custom test patterns can be created using any paint program that can read and write Windows bitmap files. Always start with a pure saturated blue background (RGB value of red = 0, green = 0, blue = 255) for a transparent background. Capture any program's output by pressing ALT+ PrintScreen, then paste into the Windows Paint program and save as a bitmap. For example: 1) Run the MAX4455 EV kit software. 2) Click the View Channel 0 button ( 3) Draw some luma bars ( palette (optional). or ). ) to use as a drawing

4) Locate your monitor's overscan boundary by pointing the camera at a black field, choose a contrasting drawing color ( ), select the free-hand drawing tool ( ), and drag the mouse around the edges of the on-screen display (optional). 5) Click the Save All button ( screen display memory. ), saving the empty on-
6) Edit the saved bitmap using any suitable paint program. 7) Load your newly created test pattern using the Load All button ( ). The test pattern is copied into the on-screen display memory.
Using Shared Memory
The MAX4455 can insert a horizontal band of on-screen display information from a different channel. This example draws vertical bars on channel 0 and horizontal bars on channel 2, then shares part of the channel 0 memory into the channel 2 display. 1) Click the View Channel 0 button ( ). 2) Maximize the window. 3) Click the Vertical luma bars ( ) drawing tool, and drag the mouse from the upper-left corner of the drawing area to the lower-right corner of the drawing area. (Once drawing begins, minimize the window to improve drawing speed.) 4) Click the View Channel 2 button ( 5) Maximize the window. ).

Writing a Single Channel
The single-channel screen includes the drawing tools, plus shared memory, vertical and horizontal offset, reading on-screen display memory, and display inhibit. Due to the severely limited bandwidth of the parallel port, the MAX4455 EV kit software time-stamp function is not offered for the multiple-write screen (see the Using the Time Stamp section).

MAX4358 Crosspoint Switch
The MAX4455 EV kit is designed for use with the MAX4358 crosspoint switch. To control the MAX4358 EV kit (included in the MAX4455EVSYS), choose the MAX4358 crosspoint from the view menu (see Figure 5). Each of the outputs has a drop-down combo box to select an input signal. Each output can also be configured for unity gain or a gain of 2V/V. The setup menu lets you quickly disable all outputs, or quickly connect each output to a preset input. Due to space limitations, the MAX4358 EV kit provides BNC connectors for only four of its 16 outputs and only four of its 32 inputs. However, the entire chip is functional, and the software allows control of all channels. When expert mode is selected, the GUI provides controls for all inputs and outputs, as well as exposing the IC address pin controls.
Writing Multiple Channels
The main screen's drawing tools can draw on all eight channels of the on-screen display. Table 6 shows the buttons that enable or disable each channel. When the program starts, channel 0 is automatically enabled. The main screen has a diagnostic menu, with global settings related to low-level register access. These settings do not need to be changed.

Character Generator
The MAX4455 EV kit software can generate text labels using any standard Windows font installed on the host computer system. Typical Windows systems usually include Arial, Courier New, and Times New Roman fonts. The font selector button runs the standard Windows font selector dialog box, which lets you choose from any of the fonts installed on your system. The text color buttons set the text foreground color to luma values of 100 IRE, 74 IRE, 47 IRE, or 0 IRE.
Troubleshooting
Problem: display seems to flicker Interlaced raster scan can appear to flicker for test patterns that have sharp, single-pixel horizontal lines. Flicker is worst on small, bright, high-contrast features. Apply a digital antialiasing function across the test pattern before writing it to the MAX4455. Do not write single-pixel lines; instead, write both field 1 and field 2 of each NTSC line pair. Problem: software can't read MAX4455 EV kit Although the MAX4455 EV kit works directly with most modern computers, some systems require that the parallel port must be enabled for bidirectional mode in the BIOS setup screen. You must reboot your computer, enter BIOS setup before Windows starts, find the integrated peripherals screen, and ensure that the LPT port is configured as an ECP port. Standard and EPP parallel port settings are not compatible with the MAX4455 EV kit. Problem: switching channels causes the display to roll If the MAX4455 inserts video fill during the vertical blanking interval, it can miss the vertical sync information. The solution is to set the BLANK bit true when switching the crosspoint. Once video sync is established, set the BLANK bit false to re-enable the video fill. (Refer to the MAX4455 data sheet for more information.)
Detailed Description of Hardware
The MAX4455 EV kit consists of a MAX4455 arbitrary graphics on-screen display video generator, a synchronous dynamic RAM, a 3.3V crystal oscillator module, and a 3.3V linear regulator. Cost-sensitive applications can replace the crystal oscillator module with a 40.5MHz fundamental mode crystal. Resistor R1 sets the white video fill. (Refer to the MAX4455 data sheet for white level calculation.) The crosspoint outputs are sampled through the rightangle connector J5, or can optionally be fed through the BNC jacks. Resistor/capacitor networks such as C32-C33-R10 sample the video signals. Because the MAX4455 EV system uses a bidirectional parallel printer cable as opposed to a local microprocessor bus, Schmitt triggers are used to sharpen the rise times of the read and write strobes. These Schmitt trigger buffers are located on the MAX4358 EV kit companion board.
Design Considerations
For best picture quality, the design of a custom MAX4455 on-screen display system requires careful attention to the ground return paths. The MAX4455 video outputs switch a significant amount of current into the analog ground return. The EV kit is designed as a two-board set to accommodate customers using different video crosspoints. However, for best results, the MAX4455 should be located close to the crosspoint switch. The MAX4455 is designed to interface directly to a microprocessor. The EV kit uses the parallel port for ease of evaluation, which is not recommended for production designs. Throughput is severely limited, and the long cable requires Schmitt trigger buffers to clean up the read/write strobes.
