Linear Technology PLLWizard(TM) Installation Instructions
==========================================================================


DESCRIPTION
--------------------------------------------------------------------------

The Linear Technology PLLWizard(TM) is used to communicate with the
LTC6945 and LTC6946 synthesizers.  It uses the DC590 to translate
between USB and SPI-compatible serial communications formats.

It also includes advanced PLL design and simulation capabilities.  You
may use it to:

	- Recommend part parameters based on your frequency plan
	- Design noise-optimized loop filters
	- Simulate loop frequency response and stability
	- Simulate VCO and Reference source noise
	- Simulate output noise characterisics and statistics

Refer to the included LICENSE.rtf for important usage information.


SYSTEM REQUIREMENTS
--------------------------------------------------------------------------

- Windows Operating System: Windows XP, Windows 2003 Server, Windows
  Vista, Windows 7
- Microsoft .NET 2.0 or later
- Windows Installer 3.1 or later
- Linear Technology's DC590 Demo Board


DETAILED INSTALLATION INSTRUCTIONS.  PLEASE READ!!!
--------------------------------------------------------------------------

1) DC590

You must possess a DC590 board, available from www.linear.com, to com-
municate with the PLL Demo Board.  But, PLLWizard WILL operate with
"Communication Disabled" without a DC590.



2) Microsoft .NET

You must have Microsoft .NET 2.0 or later installed on your computer.
PLLWizard will not run without it.  Note that Microsoft Windows Vista and
Windows 7 has at least version 3.5 preinstalled. 

To manually determine your version of .NET using Windows XP, click

	Start Menu -> Control Panel -> Add or Remove Programs

	or

	Start Menu -> Settings -> Control Panel -> Add or Remove Programs

Depending upon your .NET version, choose one of two PLLWizard setup
programs below.  Either setup program will automatically install Microsoft
.NET if a compatible .NET version is NOT FOUND.  But, the installation
source depends upon which file you downloaded from Linear Technology's
website.  You should pick one of the following two choices, depending upon
your version of .NET.

   | Downloaded Filename          | .NET Source
--------------------------------------------------------------------------
(a)| PLLWizardSetup.exe           | latest downloaded from Microsoft
(b)| PLLWizardSetup_withNet20.exe | 2.0 SP2 included (much larger file
                                  | size)

Choose (a) if you:
	-have .NET 2.0 or later, or have Vista or Windows 7, or
	-do NOT have .NET 2.0 but want the latest .NET installed.

Choose (b) if you:
	-have less than .NET 2.0, and want faster installation (no
	 additional Microsoft downloads are needed, but the file size
	 is much larger than (b)).


3) Run PLLWizard Setup File

Run "PLLWizardSetup" or "PLLWizardSetup_withNet20" to verify/install
Microsoft .NET and the PLLWizard.  The setup program will create an
"LTC" sub-menu in your Program Files menu.  Click

   LTC->PLLWizard

to run the software.

Refer to the Help menu for software operation.  Refer to the appropriate
Demo Circuit Quick Start Guide for hardware connection instructions.


INSTALLATION TROUBLESHOOTING
--------------------------------------------------------------------------

Symptom:  Unable to install.  A popup states “Another version of this
          product is already installed….”

Solution: You have a previous version of the application already in-
          stalled which the installer could not remove.  Uninstall by
          selecting “Uninstall PLLWizard” in the LTC program group.  Or,
          uninstall by using Add/Remove Programs in the Windows Control
          Panel.


Symptom:  Installation finishes but the PLLWizard™ application exits with
          an error.

Solution: Microsoft .NET 2.0 or later is not installed.  This can be
          caused by a .NET installation error, or by executing PLLWizard
          setup without Administrator privileges.  Ensure .NET 2.0 or
          later is installed and/or run PLLWizardSetup with Administrator
          privileges.


Symptom:  After installation, PLLWizard fails to start and/or Windows dis-
          plays a message stating "PLLWizard has stopped working".

Solution: Installation was not successfull.  When upgrading from to ver-
          sions 1.5.0 and greater, several system files (dll's) may not be
          copied correctly.  Uninstall PLLWizard by selecting “Uninstall
          PLLWizard” in the LTC program group. Re-install by running
          PLLWizardSetup.


Symptom:  After installation, PLLWizard fails to start and/or Windows dis-
          plays a message stating "PLLWizard has stopped working".

Solution: Early versions of PLLWizard installed a driver in the wrong lo-
          cation which prevents operation of later versions.  Delete the
          file "ftd2xx.dll" from
             Program Files (x86)\LTC\PLLWizard
             or
             Program Files\LTC\PLLWizard
