1.2 Quick-Start Setup Procedure
1.2.1 Hardware Setup
1. Connect the provided 5-VDC power supply to the barrel connector (J8) of the TSW4806. If using the
banana jacks, connect the positive end to J10 and the negative end to J9.
2. Make sure the four dip switches (SW1) are in the factory default position (all up). This corresponds to
an address of 0000 and is also indicated by four LED’s, all of which indicate OFF. The address for the
on-board EEPROM is selected by the CPLD, dependant upon the switch settings.
3. After power-up, the 5-VDC LED illuminates. The on-board CPLD automatically loads the LMK04806
from the configuration file stored in the EEPROM at the location determined by DIPSWITCH, SW1.
After the LMK is configured, the green LOCK LED turns on. This indicates that the PLL of the
LMK04806 is locked to the 10-MHz on-board reference source. The output SMA’s now provide the
following frequencies:
J7 – 61.44-MHz CMOS output. AC coupled, from CLKOUT10P of LMK04806.
J15 – 61.44-MHz CMOS output. AC coupled, from CLKOUT10N of LMK04806.
J17 – 61.44-MHz CMOS output from CLKOUT11P of LMK04806.
J4 – 122.88-MHz CMOS output from CLKOUT0P of LMK04806.
J1 – 245.76-MHz CMOS output from CLKOUT5P of LMK04806.
J2 – 491.52-MHz CMOS output. AC coupled, from CLKOUT3P of LMK04806.
J3 – 491.52-MHz CMOS output. AC coupled, from CLKOUT3N of LMK04806.
J6 – 491.52-MHz CMOS output from CLKOUT2P of LMK04806.
Note: If the LOCK LED does not turn on after power up, ensure the four dip switches are set to 0000
(all in the up position) and push the reset button (SW2).
2 Software Control
This section provides installation instructions and explanations of the TSW4806 GUI. Enable the GUI
control by connecting the provided mini-USB cable between the host PC and J13 of the EVM.
2.1 Installation Instructions
1. Download the software from the EVM product page on www.ti.com. Find the page by searching for
TSW4806EVM. The software is listed under the Related Products section on the TI Software tab.
2. Extract the files from the zip file titled TSW4806 GUI vXpY Installer.zip where XpY represents the
version number.
3. Run setup.exe and follow the installation prompts.
4. Start the GUI by going to Start menu → All Programs → TSW4806 GUI vxpx. Double click on
TSW4806 GUI.exe.
5. When plugging the board into the computer through the USB cable for the first time, the USB drivers
must be installed.
Windows
®
XP: If Windows XP does not automatically install the drivers, follow the on-screen prompts and
install them. Do not let Windows XP search Microsoft Updates for the drivers, but do let Windows XP
install the drivers automatically.
Windows 7: After installing the TSW4806 GUI, Windows 7 automatically installs the drivers for the EVM.
• If not already connected, connect the provided 5-VDC power supply to J8 and the other end to 110-
120 VAC source.
2.2 Software Operation
The TSW4806 GUI programs the LMK04806 to desired outputs other than the default power up condition
described in Section 2.1. The on-board EEPROM is also programmed from the GUI, including custom
setting options. The GUI controls are split between different tabs for a simplified interface. Detailed
descriptions for each tab are given below.
