Abstract
• One of the major goals was to examine the current technologies and it’s boundaries .
• The road so far :
– Getting to know today's technology and look up parts that are 100GB/s compatible
– Studying the theoretical aspect of the Phase Lock Loop– Testing the PLL in an Evaluation Board– Measuring low frequency signals ranging 3~4GB/s– Summing up the results and recommending suitable technology
to upgrade to 100GB/s
• Getting to know today's technology and look up parts that are 100GB/s compatible
We need to understand how the transmitter, receiver and medium work in 25GB/s transfer rate
What kind of components should we adapt for high frequency ?Transistors, Diodes, Mixers, Counters, Flip-Flops, Amplifiers ...
What are their properties and how to catalogue them ?
•Studying the theoretical aspect of the Phase Lock Loop
What is a PLL ? PLL is a control system that generates a signal that has a fixed relation to the phase of a "reference" signal, it responds to both the frequency and the phase changes of the input signals
How it’s related to our project ?
• Testing the PLL in an Evaluation Board
We’ll examine and work with ADF4350 PLL in particular
The goal is to use the PLL in a Eval-ADF4350EB1Z evaluation Board
Testing it in a free running mode and in locked mode
Different frequencies…
Relaxation period and stability for each frequency

•Measuring low frequency signals
Measuring low frequency signals ranging 3~4 GHz
Generate signals using HP-8133A Pulse generator
Infiniium DSO80204B Oscilloscope to measure signals
Understanding the measuring methods to be able to chose the next generation measuring technology
•Summing up the results and conclusions
Gathering useful 100GB/s compatible devices on one catalogue
Suggesting ideas to how would be possible to work in 100GHz frequency with a stable signal
Suggesting tools and ways to measure a signal in a high frequency of 100GHz
TimelineWe’ve created a grant timeline in order to keep track of our work
Estimated timeline:
Examining today’s technology 18/03 to 08/04Looking up devices 08/04 to 20/04Learning about PLL 22/04 to 07/05ADF4350 Evaluation Board 13/05 to 08/06Measuring Signals 06/06 to 21/06
