Detailed Description of Software User-Interface Panel The user interface (Figure 1) is easy to operate; use the mouse, or press the Tab key to navigate with the arrow keys. Each of the buttons corresponds to bits in the command and configuration bytes. By clicking on them, the correct I2C-compatible write operation is generated to update the internal registers of the MAX4399. The Interface box indicates the current I2C-compatible bus Status, Device Address, Register Address, and the Data Sent/Received, for the last read/write operation. This data is used to confirm proper device operation. The MAX4399 EV kit software splits and groups the functions of the MAX4399 into four separate categories. TV, VCR, AUX, and Configuration functions can be accessed by selecting the appropriate tab at the top left of the MAX4399 EV kit software main window. The TV, VCR, and AUX panels of the MAX4399 EV kit software are again split into two sections (Video Control and Audio Control). The device status registers (refer to the MAX4399 datasheet for status register information) are displayed in the MAX4399 status panel at the lower right of the main window. To read the status register, click the Read Status button or check the Automatic Status Read checkbox to automatically read the status register every 250ms. Click the POR Reset button to reset the MAX4399 registers and EV kit software to their power-on-reset configuration. Enable interrupts by checking the Enable Interrupt checkbox in the Interrupt Status panel (Figure 1, right). The message Interrupt Detected will appear when the MAX4399 generates a valid interrupt (refer to the MAX4399 data sheet) and the Enable Interrupt checkbox is checked. Clear this interrupt by clicking the Clear button. Note: Words in boldface are user-selectable features in the software. _______________________________________________________________________________________ 3 Evaluates: MAX4399 aging the EV kit or your computer, do not use a 25-pin SCSI port or any other connector that is physically similar to the 25-pin parallel printer port.

MAX4399 EV Kit Software Main Window (AUX Control Panel) TV Controls (Video Control) VCR/AUX Controls (Video Control) The Video Control panel of the MAX4399 EV kit software (Figure 1) allows the user to route selected signals to the TV SCART connector. Other functions such as RGB Gain, Chrominance Bias at R/C Input, Fast Switching, Slow Switching, and Pulldown TV_R/C_Out can also be changed through the Video Control panel. Manipulate the pulldown menus and checkboxes to achieve the desired result. The VCR (Figure 2) and AUX (Figure 3) panel of the MAX4399 EV kit software are identical in function with the exception of the SCART output that is being controlled. SCART output signals (VCR_Y/CVBS_out and VCR_R/C_out), Chrominance Bias at R/C Input, Slow Switching, and Pulldown VCR_R/C_Out functions can all be accessed through the Video Control panel. TV Controls (Audio Control) VCR/AUX Controls (Audio Control) The Audio Control panel of the MAX4399 EV kit software allows the user to adjust various audio characteristics of the TV output. Adjust the volume by moving the Volume Control slider, or enter a number in the edit box below the Volume Control slider. Input Source selection, Mono Switch Settings, a Mute function, the Zero Crossing Detector, a Bypass Phono Volume Control, and a Bypass TV Volume Control function can also be accessed from the Audio Control panel (refer to the MAX4399 datasheet for a description of each of these functions). Adjust the Input Source, Mono Switch Settings, and volume (Volume Control) through the Audio Control panel of the MAX4399 EV kit software. Configuration Controls Selecting the Configuration tab (Figure 4) of the MAX4399 EV kit software allows the user to adjust configuration features of the MAX4399. Checking desired checkboxes in the Output Enable panel enables selected outputs of the MAX4399. A bias voltage may also be applied at the R/C input of the encoder (Chrominance Bias applied at ENC_R/C_IN). _______________________________________________________________________________________ 5 Evaluates: MAX4399 MAX4399 Evaluation System/Evaluation Kit Figure 4. MAX4399 EV Kit Software Main Window (Configuration/Encoder) The MAX4399 EV kit software continuously polls the MAX4399 to make sure that the two boards have not become inadvertently disconnected. An undesired result of this polling is constant activity on the I2C-compatible bus. This feature may make it difficult to monitor the I2C-compatible interface for desired bit patterns. Disable this feature by checking the Disable Software DUT Detection checkbox. Simple I2C-Compatible Commands There are two methods for communicating with the MAX4399: through the normal user-interface panel or through the I2C-compatible commands available by selecting the 2-Wire Interface Diagnostic item from the Options pulldown menu. A display pops up that allows the SMBus/I2C-compatible protocols, such as Read Byte and Write Byte, to be executed. The dialog boxes accept numeric data in binary, decimal, or hexadecimal. Hexadecimal numbers should be prefixed by $ or 0x. Binary numbers must be exactly 6 eight digits. See Figure 5 for an example of this tool. In this example, the software is reading data (0xC0) from Device Address 0x95, Register Address 0x0E. The above sequence reads the status register of the MAX4399. Note: In places where the slave address asks for an 8-bit value, it must be the 7-bit slave address of the MAX4399 as determined by DEV_ADDR with the last bit set to 1 for a read operation or a zero for a write. Refer to the MAX4399 datasheet for a complete list of registers and functions. Detailed Description of Hardware The MAX4399 EV kit is an assembled and tested PC board that demonstrates the MAX4399 triple SCART switch matrix. It routes audio, video, and control signals between an MPEG decoder and the TV, VCR, and AUX SCART connectors. All video connections are made through 75Ω controlled-impedance traces. _______________________________________________________________________________________ MAX4399 Evaluation System/Evaluation Kit Evaluates: MAX4399 Figure 5. Simple SMBusReadByte Operation Using the Included 2-Wire Interface Diagnostics Connect a TV, VCR, and Auxiliary unit (DVD player, 2nd VCR, camcorder, etc.) to the TV, VCR, and AUX SCART connectors, respectively (refer to the MAX4399 datasheet for SCART connector pinouts). MPEG decoder video connections are made through the 75Ω BNCs with the ENC prefix. MPEG decoder audio connections are made through the ENC LT and ENC RT (J8 and J6) RCA connectors. Monitor the phono audio outputs through the PHONO RT and PHONO LT (J5 and J7) RCA connectors. Monitor the R/C inputs of the TV, VCR, and AUX connections through the TV_R/C_IN, VCR_R/C_IN, and AUX_R/C_IN BNCs, respectively. Apply a satellite dish tone input through the ST AUX IN (J10) RCA connector. Monitor the RF modulator mono audio output through the RF MONO RCA connector. Monitor the RF modulator composite video output through the RF_CVBS_OUT BNC. Address Selection Jumper JU4 sets the MAX4399 slave address. The default address is 1001 011Y (DEV_ADDR = V_DIG). See Table 1 for a complete list of addresses. Note: The first 7 bits shown are the address. Y (bit 0) is the SMBus read/write bit. This bit is a 1 for a read operation or a zero for a write. Table 1.
