A surfacemounted DS31400 and careful layout provide maximum signal integrity. An on-board low-phase-noise Stratum 3 quality oscillator is provided for device compliance evaluation. Additionally, the board can accept an external oscillator input for testing alternate oscillators and oscillator frequencies. All eight DS31400 input clocks are accessible through a combination of SMA and SMB connectors. These input clocks are terminated on-board as four 100I differential AC-coupled and four single-ended 50I DC-coupled inputs to allow easy evaluation of a wide range of input clock signal formats. All 14 DS31400 output clocks are accessible through a combination of SMA and SMB connectors to allow easy evaluation of the device’s CML, LVDS/LVPECL, and CMOS output clock signals. On-board LEDs indicate interrupt, DPLL lock, selected reference fail, and GPIO output status. Additionally, the GPIO, interrupt, and JTAG I/O signals are also accessible through header pins. Finally, an onboard microcontroller and USB interface provide easy configuration and monitoring of the DS31400 through a WindowsM-based software application.

Contact that factory for DS31400 configuration scripts for use with 10.24MHz and 20.48MHz oscillators if needed. Additional note: Some boards have been built and shipped with rev A1 DS31400 ICs and 20.48MHz oscillators for best jitter performance. On these boards DIP switch SW2.SWITCH1 is set to 1 at the factory and must remain set to 1 for proper operation. When the DS31400 demo kit software determines SW2.SWITCH1 = 1, it automatically configures a rev A1 DS31400 for operation with a 20.48MHz oscillator. __________________________________________________________________ Maxim Integrated Products 7 DS31400 Demo Kit Evaluates: DS31400 2.6 GPIO and Interrupt Header The DS31400 GPIO bidirectional pins and INTREQ output pin are available on the 10-pin header J52.

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. The DS31400 demo kit software installation consists of the following two steps: 1) Install the DS31400 demo kit software application. 2) Install the DS31400 demo kit virtual COM port driver (for USB connection to the board). The following sections describe in detail how to perform each of these steps. 4.1 Software Application Installation At this time the DS31400 demo kit software is only supported on Windows 2000 and Windows XP operating systems. Download the latest version of the demo kit software at www.maxim-ic.com/DS31400DK or request it from Maxim applications support. To install the software, open the installer zip file and run setup.exe. __________________________________________________________________ Maxim Integrated Products 8 DS31400 Demo Kit Evaluates: DS31400 4.2 USB Virtual COM Port Device Driver Installation After the GUI application has been installed on the PC, apply power to the DS31400 demo kit board and connect its USB port to a USB port of the PC. Then follow these steps: • A Found New Hardware message appears in the notification area of the Windows taskbar, and then the Found New Hardware Wizard appears. • Select No when asked if you want to connect to Windows Update to look for the driver. • Click Next. • Select Install from a list or specific location. • Click Next. • Select Search for the best driver in these locations and check include this location in the search, then browse to the folder where the DS31400 demo kit software was installed. The default installation folder can be reached by browsing My Computer à Program Files à Maxim à DS31400 Demo Kit. (The driver file is HC9S08JMxx.inf, but Windows only needs to know the name of the folder in which to look for this file.) • Click Next. • If a message appears to indicate that the software has not passed logo testing, click Continue Anyway. That should complete the virtual COM port device driver installation. After following these steps, the DS31400 demo kit software should be ready to communicate with the board. 4.3 Command Line Options The software has these command line options: -l <filepath> specifies an alternate log file example: DS31400DK.exe –l “mylog.mfg” To add command line options to the DS31400 demo kit shortcut the installer adds to the desktop, right-click on the shortcut and select Properties. In the Shortcut tab, at the end of the text in the Target text box, add a space followed by the command line option. 5. Software Application Overview The DS31400 demo kit software provides an easy and interactive way to evaluate the DS31400 by using hierarchical menus to configure the device and monitor its status. The following sections briefly describe each of the major application menus. Note: In each menu, when the mouse cursor is placed over a configuration or status field, more information is displayed about that field, such as associated DS31400 registers or valid numerical range. 5.1 Main Menu The main menu window, shown in Figure 2, is displayed when the program is started. This menu provides an overview of the DS31400 configuration and status. Additionally, it provides access to the application submenus that are used to perform detailed device configuration. The major features located on the main menu include the following: • Port drop-down list (upper left corner) When the program starts, a scan is performed of the computer’s USB-connected virtual ports. Those ports connected to DS314xxDK boards are displayed in the Port drop-down list. • Demo Mode checkbox (upper left corner) When the program starts it is initially in Demo Mode. In Demo Mode the software is not connected to the demo kit board. In this mode the software can be used to investigate DS31400 configuration options or to develop a DS31400 configuration script without the need to connect a board. When the Demo Mode checkbox is unchecked, the GUI application establishes communication with the demo kit board through the port displayed in the Port drop-down list. In this mode all menu configuration changes are translated into DS31400 register writes that are then written to the DS31400 on the board. __________________________________________________________________ Maxim Integrated Products 9 DS31400 Demo Kit Evaluates: DS31400 Figure 2. Main Menu Window • Enable Polling checkbox (upper left corner) When the Demo Mode checkbox is unchecked, if the Enable Polling checkbox is checked, the status registers in the DS31400 are periodically polled, and the corresponding status fields in the software are automatically updated. • Reset checkbox (upper left corner) This checkbox directly controls the MCR1.RST bit in the DS31400. When this checkbox is checked, the entire DS31400 is reset to its power-on default state. • Master Clock group box/Frequency Adjust spin box Any known frequency error in the local oscillator can be calibrated out inside the DS31400 by setting the ppm value of the error in the Frequency Adjust spin box. • Input Clocks group box This section of the main menu provides an overview of how each input clock is configured and its current status. Additionally, the DPLL priority for each input clock can be set using the corresponding drop-down list. Finally, the input frame sync capabilities of the DS31400 can be configured here. For each input clock, a submenu containing detailed configuration and status information is accessed by pressing the corresponding numbered button in the # column on the left side. _________________________________________________________________ Maxim Integrated Products 10 DS31400 Demo Kit Evaluates: DS31400 Just to the right of the input clock numbers, in the Status column, are software LEDs that indicate the state of each input as reported by its input monitor. These LEDs are red when the input clock is invalid. When a clock of the correct frequency is applied to an input, the associated LED turns yellow when activity is detected and green when the input clock frequency is found to be within range. If an input is disqualified by one of the DPLLs because the DPLL could not lock to it, the LED turns magenta. Important Note: If the Status checkbox for an input clock is not red, green, yellow, or magenta, the input clock is disabled. To enable the input clock, check the Enable checkbox to the left of the Status checkbox. • DPLL1 and DPLL2 group boxes The key features of each DPLL can be configured in the DPLL section of the main menu, including acquisition bandwidth, locked bandwidth, automatic or manual input clock selection, and automatic or manual DPLL state selection. Also, key status information is reported here including current selected reference (Sel Ref), priority 1, 2, and 3 backup references (Priority 1, Priority 2, Priority 3 edit boxes), and DPLL state (State button), phase (Phase (deg) edit box), and frequency (Freq (ppm) edit box). The State, Sel Ref Fail, and Phase Mon buttons represent latched status bits in the device. When the button is red, the corresponding latched status bit has been set in the DS31400 since the last time the button was pressed. Pressing the button clears the latched status bit and changes the color of the button back to green. The State button indicates the state of the DPLL has changed. Sel Ref Fail indicates the selected reference has failed. Phase Mon indicates the phase monitor limit has been exceeded. The Revertive checkbox configures the DPLL for revertive or nonrevertive switching among input clocks. When Auto BW = 1, the DPLL uses the acquisition bandwidth during pull-in and the locked bandwidth when phase locked. When Auto BW = 0, the DPLL uses the locked bandwidth all the time. For each DPLL a submenu containing additional configuration and status information is accessed by pressing the DPLLx button (where x is the output clock number) located in the top-left corner of the DPLLx group box. • Output Clocks (OCx group boxes) The frequency of each of the DS31400’s 14 output clocks is displayed in the corresponding output clock section. Additionally, the output enable for each output clock is controlled here. For each output clock, a submenu containing detailed configuration fields is accessed by pressing the corresponding OCx button (where x is the output clock number) located in the upper left corner of each OCx group box. To identify an invalid output clock configuration, the output clock frequency field turns red when that output clock has been configured to an invalid frequency. A frequency is invalid when it is too fast for the output driver: > 125MHz for CMOS, > 312.5MHz for LVDS/LVPECL, or > 750MHz for CML. • Frame Sync Outputs group box The most common features of the DS31400 FSYNC and MFSYNC outputs are configured in this section of the main menu. A submenu providing additional configuration information is accessed by pressing the Frame Sync Outputs button located in the top left of the Frame Sync Outputs group box. • Configuration Script buttons The Run Config Script button launches a submenu that allows execution of a DS31400 configuration script. These scripts can configure the entire IC (full configuration script) or only a portion of the IC (partial configuration script). The Create Config Script button launches a submenu from which a full-chip configuration script can be generated. • View Log File button The View Log File button launches a text editor containing the DS31400 log file. This log file contains a history of DS31400 register writes performed since the application was launched. • Register View button The Register View button launches a submenu that provides register level access to all DS31400 registers. • I/O Pins button The I/O Pins button launches a submenu that can be used to configure the DS31400 GPIO, LOCK, and SRFAIL outputs. • Disable All Outputs button Pressing the Disable All Outputs button disables all DS31400 outputs (all Enable checkboxes in the OCx group boxes are cleared). _________________________________________________________________ Maxim Integrated Products 11 DS31400 Demo Kit Evaluates: DS31400 5.2 Input Clock Configuration Menu The Input Clock Configuration submenu window, as shown in Figure 3, is used to perform detailed configuration of an input clock.

I/O Pin Configuration Menu _________________________________________________________________ Maxim Integrated Products 16 DS31400 Demo Kit Evaluates: DS31400 5.7 Register View Menu When the Register View button in the lower left corner of the main window is pressed, the Register View window appears (Figure 8). In this window the DS31400’s entire register set can be viewed and manually written as needed. The large grid that takes up most of the window displays the DS31400 register map. For each register, its hexadecimal address in square brackets is followed by its register name and its contents in two-digit hex format. When a register is clicked in the main register grid, its register description and fields are displayed at the bottom of the window. The Register View window supports the following actions: • Read a register. Select the register in the register map. • Read a register field. Select the register in the map or the register field at the bottom of the window. • Read all registers. Press the Read All button. • Write a register. Double-click the register name in the register map and enter the value to be written. • Write a register field. Select the register, double-click the field, and enter the value to be written. • Write a multiregister field. Double-click one of the register names and enter the value for the field. • Write a complete DS31400 register dump to a text file. When using the Register View window it is important to remember that input clock, DPLL, and output clock registers are bank-switched by the ICSEL (0x0060), DPLLSEL (0x0080), and OCSEL (0x00C0) registers, respectively. See Section 8.1.4 in the DS31400 IC data sheet for more information. Figure 8. Register View Menu _________________________________________________________________ Maxim Integrated Products 17 DS31400 Demo Kit Evaluates: DS31400 5.8 Configuration Scripts and Log File 5.8.1 Configuration Log File Every write command issued by the software to the DS31400 demo kit board is logged in file DS31400DKLog.mfg located in the same folder as the software executable. If default values were used during installation, this folder is C:\Program Files\Maxim\DS31400 Demo Kit. The log file can be viewed in Notepad by pressing the View Log File button in the lower left corner of the main window. Command line option “-l <filepath>” can be used to cause the software to write to a file other than DS31400DKLog.mfg, as described in the 4.3 Command Line Options section. 5.8.2 Configuration Scripts Configuration scripts are useful for quickly configuring the DS31400 without having to remember all the required settings. Two types of configuration scripts are possible: full and partial. A full configuration script can start with the DS31400 in its power-on default state and configure every aspect of the device to bring it to a desired state. To make a full configuration script, run the software, uncheck the Demo Mode checkbox, initialize the device, then configure the device using the demo kit software. Next, press the Create Config Script button in the lower left corner of the main window, specify the file name and location, and then press the Create button. The new script is then displayed in Notepad. A partial configuration file only affects a subset of the DS31400 device settings. To make a partial configuration script, press the View Log File button in the main window to view the log file, press Ctrl-End to jump to the end of the file, and then add to the end of the file a comment line (starting with a semicolon) to delimit the start of the desired configuration. Then save and exit the log file. Next, configure the device using the demo kit software fields. Finally, view the log file again, jump to the end, and copy everything from the previously made delimiter to the end of the file into a new .mfg file. To run a configuration script, press the Run Config Script button in the lower left corner of the main window, specify the file name and location, then press the Execute button. Note that when the Demo Mode checkbox is changed from checked to unchecked, during the Initializing the DS31400 step, the software runs configuration script startup.mfg located in the same directory as the software executable. The startup.mfg file can be edited or replaced as needed to change the initial configuration of the device. Be aware, however, that the section of the startup.mfg file labeled “Required Initialization” must be executed after device power-up or reset for the DS31400 to operate correctly. 6. DS31400 Demo Kit Errata 6.1 Revision 03A0 Board On the revision 03A0 board the traces for LVDS/LVPECL outputs OC4 to OC7 are routed beside each other for a significant distance. This results in significant coupling between neighboring outputs and higher jitter. For lowest jitter results with these outputs, use only OC4 and OC7, which are farthest apart. _________________________________________________________________ Maxim Integrated Products 18 DS31400 Demo Kit Evaluates: DS31400 7.
