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 MAX9860 EV kit is fully assembled and tested. Follow the steps below to verify board operation before exercising the full features of the MAX9860: 1) Verify that all of the jumpers are set in their default positions, as shown in Table 1. 2) Connect one TOSLINK optical cable between the digital audio equipment input and the J1 module on the EV kit board. 3) Connect the other TOSLINK optical cable between the digital audio equipment output and the J2 module on the EV kit board. 4) Connect one analog audio source to the MICLP and MICLN pads on the EV kit board. Connect the MICLN pad to GND for single-ended microphone input. 5) Connect the other analog audio source to the MICRP and MICRN pads on the EV kit board. Connect the MICRN to GND for single-ended microphone input. 6) Connect the speaker to the OUTP and OUTN pads on the EV kit board. 7) Set the digital audio equipment audio output and input sampling frequency to 48kHz. 8) Enable the digital audio equipment input and output. 9) Enable the two analog audio sources. 10) Visit www.maxim-ic.com/evkitsoftware to download the latest version of the EV kit software, 9860Rxx.ZIP. 11) Install the MAX9860 evaluation software on your computer by running the INSTALL.EXE program. The program files are copied and icons are created in the Windows Start menu. 12) Connect the USB cable from the PC to the EV kit board. A New Hardware Found window pops up when installing the USB driver for the first time. If a window is not seen that is similar to the one described above after 30s, remove the USB cable from the board and reconnect it. Administrator privileges are required to install the USB device driver on Windows. 13) Follow the directions of the Found New Hardware window to install the USB device driver. Manually specify the location of the device driver to be C:\Program Files\MAX9860 (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. 14) Start the EV kit software by opening its icon in the Start | Programs menu. 15) The EV kit software main window appears as shown in Figure 1. Verify that the message MAX9860: Connected is displayed on the status bar at the bottom of the software’s main window. 16) In the Clock Sources group box, click on the Recovered Master Clock radio button. 17) Press the Configure button. 18) On the top-right corner of the software’s main window, select Enabled from the drop-down list. 19) Verify that audio from the digital audio equipment is output at the speaker and the two analog audio sources are output to the digital audio equipment. 4 _______________________________________________________________________________________ MAX9860 Evaluation Kit Software Main Window On the top of the main window, press the Read All button to read all of the MAX9860 register values and update the GUI. Press Reset to reset the EV kit hardware. Press Connected to set up the connection between the EV kit and the software application. The drop-down list lets a user enable or disable the MAX9860. The Device Status group box reports the status of various device functions. Check/uncheck the checkboxes to enable/disable the hardware interrupts for each status flag. The lower side of the main window includes six tabs. On each tab sheet, the user can exercise a group of related configurations and check the register values. Each control on the GUI generates the expected read and/or write operations on the internal registers of the MAX9860 and the CS8427 digital audio transceiver. File Menu Select the Save Configuration menu item to save the current EV kit configuration to a text file that can be loaded at a later time. Select Load Configuration to reload settings from a saved file. Select Exit to exit the application. Deselect the Auto Read Status menu item before using the command module interface. The I2C dialog boxes accept numeric data in binary, decimal, or hexadecimal. Hexadecimal numbers should be prefixed by $ or 0x. Binary numbers must be exactly eight digits. See Figure 2 for an example of this control method. Help Menu Select Help for information about this software. Digital Audio Interface and Clocking Tab The Digital Audio Interface and Clocking tab sheet (Figure 1) contains the master clock (MCLK) and digital audio interface selections for the MAX9860. A user can select an automatic typical interface configuration or manually configure the device according to specific requirements. Playback / Sidetone Tab The Playback / Sidetone tab sheet (Figure 3) includes the DAC enable and gain controls. It also includes the sidetone enable and level controls. Record Tab The Record tab sheet (Figure 4) controls the functionality of the ADC and the microphone circuitry on the MAX9860. Digital Filters Tab View Menu The Digital Filters tab sheet (Figure 5) controls the functionality of the DAC and ADC voice filters on the MAX9860. Options Menu The AGC / NG tab sheet (Figure 6) includes the settings for the noise gate and the automatic gain control on the MAX9860. Select the View Transceiver Registers menu item to display or hide the CS8427 tab to change the digital audio transceiver registers. Select the Power On Reset menu item to reset the MAX9860 to its power-on state. Select Read Status to read the MAX9860 status registers. Select Auto Read Status to enable the automatic read of the MAX9860 status registers. Select Auto Connect to automatically set up the connection between the EV kit and the software application in case the connection is lost. AGC / NG Tab Registers Tab Tools Menu The Registers tab sheet (Figure 7) displays all of the MAX9860 register values on one page. To change a register value, type in the new value in the appropriate edit box and press the Enter key on the keyboard, or click the bit names on the GUI. Select Debug Mode to bring up the Maxim Command Module Interface window. The interface allows I2C operations, such as read byte and write byte, to be executed. The CS8427 tab sheet (Figure 8) displays the MAX9860 EV kit-related CS8427 register values on one page. To change a register value, type in the new value in the appropriate edit box and press Enter or click the bit names on the GUI. Select the Reconnect to EVKIT menu item to set up the connection between the EV kit and the software application.

The EV kit provides translation between the digital audio signals and optical S/PDIF signals to allow easy connection with consumer electronics devices. See Table 1 for a description of all EV kit jumper configurations. Clocking On-Board Clock The EV kit has one 12.288MHz and one 13MHz clock oscillator on the board to provide flexible master-clock selections for the MAX9860. Recovered Clock When the S/PDIF IN has a digital audio input and the S/PDIF transceiver is in operation, the recovered clock from the S/PDIF transceiver can be used as the master clock for the MAX9860. External Clocks Connect an external clock source to the jumper JU8 center pin on the 5th row to drive the MAX9860’s MCLK pin without using the on-board oscillator. The user must type in the correct clock frequency in the MCLK Frequency edit box. Table 1.
