DEMO MANUAL DC1705C
LTC6946
Ultralow Noise and Spurious Integer-N
Frequency Synthesizer with Integrated VCO
DESCRIPTION
DC1705C features the LTC®6946, an ultralow noise and
spurious integer-N frequency synthesizer with integrated
VCO. The VCO uses no external components and is internally calibrated without external system support.
output buffer (REF OUT), and the differential RF output
(RF+ and RF –). A DC590 USB serial controller board is
used for SPI communication with the LTC6946, controlled
by the supplied PLLWizard™ software.
There are four options of the DC1705C, one for each version of the LTC6946. Table 1 summarizes the available
DC1705C options.
Design files for this circuit board are available at
http://www.linear.com/demo/DC1705C
Each DC1705C provides 50Ω SMA connectors for the
reference frequency input, fREF (REF+ IN), the reference

DETAILS
Low Noise and Spur-Free 3.3V, 115mA
Low Noise and Spur-Free 5V, 45mA
Low Noise 10MHz or 100MHz*, 6dBm into 50Ω
(Note 1)
Frequency = fREF, 0dBm
Frequency: 900MHz*, Power: 0dBm, Frequency
Range: Depends on the version of the LTC6946
device – refer to Table 1, Step Size: 200kHz*
Set by Loop Filter Component Values 47kHz*
* These frequencies are for the DC1705C pllset files included with PLLWizard.
Note 1: A low noise 10MHz or 100MHz reference frequency, such as the Wenzel 501-04608A or 501-04516D OCXO, is recommended. If using a different
frequency, make sure to update the fREF and R_DIV boxes under the System tab in PLLWizard so that fPFD is still 1MHz. For example, if a 20MHz clock is
used, fREF should be changed to 20MHz and R_DIV to 20. REF BST and FILT under the System tab in PLLWizard might need to be changed if the reference
frequency and/or power is different than what is recommended in the table above. More information can be found in the LTC6946 data sheet.

DEMO MANUAL DC1705C
QUICK START PROCEDURE
The DC590 and PLLWizard application are required to
control the DC1705C through a personal computer (PC).
DC590 Configuration
The DC590’s QuikEval™ drivers must be installed before
the DC590 will be able to communicate with the LTC6946.
To configure the DC590, follow the procedure below, starting with step 1. If you have already installed the DC590
software previously, skip to step 5.
Note: Once the QuikEval software is installed, the application does not need to be executed to run PLLWizard or to
control the DC1705C.
1. Do Not plug in the DC590 before running the installation
program.
2.Download the QuikEval installation program from
http://www.linear.com/software.
3.Run the QuikEval installation program and follow the
on-screen instructions. More detailed installation information may be found in the DC590’s Quick Start guide.
4. Exit the QuikEval program once the installation is complete, as it is not needed to run the PLLWizard software.
5.Place the DC590 jumpers in the following positions:
JP4 EE Must be in the “EN” position.
JP5 ISO “ON” must be selected.
JP5 SW “ON” must be selected.
JP6 VCCIO “3.3V” must be selected. This sets the SPI
port to 3.3V operation.
6.Connect the DC590 to one of your computer’s USB
ports with the included USB cable.

PLLWizard Installation
Microsoft .NET
The PLLWizard software is used to communicate with
the LTC6946 synthesizer. It uses the DC590 to translate
between USB and SPI-compatible serial communications
formats. It also includes advanced PLL design and simulation capabilities. The following are the PLLWizard system
requirements:
You must have Microsoft .NET 2.0 or later installed on
your computer. PLLWizard will not run without it. Note that
with Windows Vista and Windows 7, you should have at
least version 3.5 pre-installed.
• Windows Operating System: Windows XP,
Windows 2003 Server, Windows Vista, Windows 7
• Microsoft .NET 2.0 or later
• Windows Installer 3.1 or later
To manually determine your version of .NET using Windows XP, click Start Menu → Settings → Control Panel
→ Add or Remove Programs.
Depending upon your .NET version, choose one of
two PLLWizard setup programs, downloaded from
http://www.linear.com/software.
• Linear Technology’s QuikEval and DC590 hardware
dc1705cfb

DEMO MANUAL DC1705C
QUICK START PROCEDURE
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.
Table 2. PLLWizard Installation File
FILE
.NET 2.0 SOURCE
PLLWizardSetup.exe
Latest Version Downloaded from Microsoft
PLLWizardSetup_net20.exe
2.0 SP2 Included (Much Larger File Size)
•Choose PLLWizardSetup if you have .NET 2.0 or later,
have Windows Vista or Windows 7, or if you have less
than .NET 2.0 but want the latest .NET installed.
•Choose PLLWizardSetup_net20 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).
The setup file will verify and/or install Microsoft .NET and
install PLLWizard. Refer to the Help menu for software
operation.

DEMO MANUAL DC1705C
QUICK START PROCEDURE
DC1705C Configuration
1. Connect an appropriate reference frequency source (at
J1) and signal analyzers (at J4 and/or J5) using the
SMA connectors (see Figure 1 and the Typical DC1705C
Requirements and Characteristics table).
2. Choose the MUTE jumper setting: JP1 - GND/3.3V MUTE
position. Select GND to mute the RF output, 3.3V to
un-mute.
3. Connect the GND, 3.3V and 5V banana jacks to a power
supply and apply power (see Figure 1 and the Typical
DC1705C Requirements and Characteristics table).
4.Connect the DC590 to the DC1705C with the provided
ribbon cable.
5.Run the PLLWizard application.
6.In PLLWizard, click File → Load Settings and point
to the appropriate pllset file. For example, if you are
using a 10MHz reference with a DC1705C-B to evaluate the LTC6946-2, load the “DC1705-B (LTC6946-2)
10MHz.pllset” file found in the PLLWizard installation
directory (typically Program Files → LTC → PLLWizard
→ Set Files).
You can then change the values of N_DIV and/or O_DIV
in PLLWizard to change the output frequency.
Troubleshooting
If the red LED does not illuminate, follow the instructions
below:
1.Verify that you are able to communicate with the
DC1705C. The bottom status line in PLLWizard should
read “LTC6946” and “Comm Enabled.” Refer to PLLWizard’s Troubleshoot and Help if not.
2.Verify that the 3.3V and 5V have the correct voltages
on them and that the reference frequency is applied to
the REF + IN SMA input.
If the red LED is on but you cannot detect an RF output,
make sure jumper JP1 is at the 3.3V position. Run Help →
Troubleshoot in PLLWizard if the problem is not resolved.
DC1705C Reconfiguration
You can redesign the frequency plan of the DC1705C using PLLWizard. You can change the loop filter as found
using PLLWizard by reinstalling the loop filter components
shown in Figure 4.
The red LED on DC1705C should turn on indicating that
the loop is locked at 900MHz.

SCHEMATIC DIAGRAM
Note: The buffers shown on sheet 2 of 2 of the schematic are used to protect the LTC6946 when communicating to it starts before powering it up. There is no
need for such circuitry if the SPI bus is not active before powering up the LTC6946. The EEPROM is for identification and is not needed to program the LTC6946.
