Page 4: Getting Started
SECTION 1.0 GETTING STARTED 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. -

Page 8: Entering Pll Frequencies
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. - Page 9 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.

Page 10: Selecting Divider Values
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. - Page 11 You have just setup Clk A for 155.52 MHz. Lets setup Clk B. Since we want 38.88 MHz as Clk B, click source B dropdown box and select PLL1. Click Divider B dropdown box and select 4. Click the Calculate button. You have just setup Clk B for 38.88 MHz.

SECTION 3.0 Using the SCMF Test Board. Introduction The SCMF Test Board is designed to measure and reconfigure the Multiple Frequency Output and Single Frequency Output family of oscillators from Cardinal Components. The SCMF Test Board consists of the following basic components. -
Page 15: Setting Up The Scmf Test Board
Lets start by setting up the SCMF Test Board for frequency measurement only. When using the SCMF Test Board as a stand-alone unit, 5 Volts DC must be applied to the board. Attach a cable from the SCMF Test Board 5 Volt input to a 5 Volt DC source. Make sure that JP3 is correct. - Page 16 If 5 volts was applied to the board and JP3 is configured correctly, it is time to install a part. Using the SC3600 adaptor socket for measuring a Single Output part or the SC3700 adaptor socket if measuring a Multiple Output part, insert the oscillator and adaptor into the ZIF socket.

Page 17: Connecting The I C Interface
3.2.2 Connecting the I C interface The SCMF Test Board has an I C connection which can be used by a microcontroller for reconfiguration and EEPROM access. The pin outs for this connection are shown if Figure 2. Please note: If there is a 3.3 volt source available, then the SClk, SData, Gnd and VI C (3.3 volts) can all be connected to the board through... -
