Equipment
Power Supply
The Power Supply should be a low noise power supply. An Agilent 6623A Triple power supply with LC filters on the
output to reduce noise was used in creating these evaluation board instructions.
Phase Noise / Spectrum Analyzer
For measuring phase noise an Agilent E5052A is recommended. An Agilent E4445A PSA Spectrum Analyzer with the
Phase Noise option is also usable although the architecture of the E5052A is superior for phase noise measurements. At
frequencies less than 100 MHz the local oscillator noise of the PSA is too high and measurements will be of the local
oscillator, not the device under test.
Oscilloscope
The oscilloscope and probes should be capable of measuring the output frequencies of interest when evaluating this
board. The Agilent Infiniium DSO81204A was used in creating these evaluation board instructions.
Reference Oscillator
The on board crystal oscillator will provide a low noise reference signal to the device at offsets greater than 1 kHz.
Note: The default loop filter has a loop bandwidth of ~60 kHz. Inside the loop bandwidth of a PLL the noise is greatly
affected by any noise on the reference oscillator (OSCin). Therefore any noise on the oscillator less than 60 kHz will be
passed through and seen on the outputs. For this reason the main output of a Signal Generator is not recommended for
driving OSCin in this setup.

Basic Operation
1) Connect a low noise 3.3 V power supply to the Vcc connector located at the top left of the board.
2) Connect 122.88 MHz signal from signal generator output to CLKin0 of board.
3) Please see Appendix B for quick start on interfacing the board. Connect PC to the uWire header.

5) Select the device by ”Select Device” “Clock Conditioners”
6) Enable the output to measure (example CLKout0 is enabled below)

7) Program the part by clicking “Keyboard Controls” “Load Device” or by pressing Ctrl+L.
***Be advised: GOE and SYNC* on the IC have internal pull-ups. Voltage dividers are used to
lower 5 V LPT ports to safe levels for the device while still programming with 3.3 V LPT ports.
When the cable is removed however, the pull-down of the voltage divider will overpower the
pullup of the GOE or SYNC*. For this reason GOE is disconnected so the cable can be
disconnected and the outputs still will be on. However, or any channels which have dividers
enabled, the SYNC* will go low and cause them to stop oscillating. Future versions of the
evaluation board have zener diodes on GOE and SYNC* to eliminate this issue.
