SECTION 1.0 GETTING STARTED
1.1 Introduction
The SCMF Test Board is an assembled and tested PC Board
That demonstrates the Multiple Output and Single Output series of
reconfigurable oscillators.
The Test Board consists of a circuit board assembly with 6
SMA connectors, which allow frequency measurement of the 6
available outputs. The board can also interface with a microcontroller
through the I2C connector for reconfiguration of the oscillators.
With optional adaptor sockets, the 14 pin SMT multiple output
and the 8 pin SMT single output oscillators can be reconfigured.
Equipment supplied with the SCMF Test Board.
Software CD for creating JEDEC files for reconfiguration.
Required Equipment.
Compatible PC running Windows 98SE/ME/2000/XP
Optional Equipment
SC3600 Socket (used to measure and reconfigure the 8 pin Single Output
SMT oscillator)
SC3700 Socket (used to measure and reconfigure the 14 pin Multiple Output
Smt oscillator)
1.2 Software Installation
Insert the enclosed CD. If Setup does not auto start, then run
Setup from the CD.
This installation will install the JEDEC Creator program.
SECTION 2.0 JEDEC Creator
2.1 Running the JEDEC Creator Program
Note: If you do not wish to create JEDEC files you can skip this section and
proceed to the Using the SCMF Test Board.
From the desktop, click on the JEDEC Creator Icon.
The program can also be run by double clicking
JedecCreator.exe from the directory from which it was loaded
during installation.
The Options screen should now be visible.
Please select the type of part to be programmed and package type. Select OK
when ready.
The main screen should now be visible.
2.1.1 Entering PLL Frequencies
The first step is to enter a PLL frequency. Allowable PLL frequencies are
from 100 MHz to 400 MHz.
Note: The calculation of a PLL frequency is very complex. Not all
frequencies have solutions. If a PLL frequency cannot be calculated, an error
message will be displayed.
Suppose we need output frequencies of 155.52 MHz, 38.88 MHz,
53.125 MHz and 106.25 MHz. Since 155.52 MHz can be divided by 4 to get
38.88 MHz and 106.25 can be divided by 2 to get 53.125, we will be using
155.52 and 106.25 as our PLL frequencies. We can now enter PLL 1 as
155.52 and PLL 2 as 106.25. Enter these frequencies into the PLL1 and
PLL2 box and hit the Calculate button. Notice that as we enter new numbers
the Calculate button turns green indicating that we have made some changes.
The screen should look like this.
The OK in the Calculated Freq box indicates that the program has
found acceptable values for the PLL frequency and we can proceed to the
next step.
2.1.2 Selecting Divider Values
One of our desired output frequencies is 155.52 MHz. Lets
setup that frequency for Output A.
Under source for Clk A, click on the drop down box. A choice
of possible source frequencies are Ref, PLL1, PLL2, PLL3. The Ref
or Reference frequency can be used as a source instead of a PLL
frequency. The Ref frequency is determined at startup when the part
was selected. If you look at the Main Screen, you will see a number
next to the Part Type. This is the Ref Frequency for this setup.
Lets select PLL1 as the source for Clk A. Next lets select a
divider for Clk A. Since we want 155.52 as an output, our divider will
be 1. You can select divider values from 1 to 127. Click on the
Calculate button and the screen should look like this.
