1. RF Phenomenon Midterm presentation Written by: Jamil Shehadeh Naseem Jamal Supervisor: Yossi Hipsh 25/6/2007

2. Block Diagram

3. Current Card

4. What are we changing? We want to redesign the card in order to illustrate and demonstrate different RF phenomenon other than the ones demonstrated by the current experiment card.

5. The new block diagram

6. The 1ns pulse generator Pulse width of 1ns with T_cycle=100ns t_rise=t_fall=0.33ns  f_knee=1GHz

7. 1 st implementation

8. 2 nd implementation

9. The new block diagram

10. faster 1:15 clock distributor The previous clock distributor is slow and doesn’t suit our design (t_rise=t_fall=1ns) S/N: NB100LVEP222 –The new faster clock distributor has t_rise=t_fall=0.3ns –Max Propagation Delay= 1.2ns

11. The new block diagram

12. Experiment Card We are going to change all the transmittion lines into differential lines due to slow PECL to TTL converters Designing a new measurement system in order to sample the different differential signals We will be using the same stack used in the old experiment

13. Circuits Some of the new features of the new system: Jitter Skew Propagation Delay

14. Jitter

15. Skew

16. Controlled Propagation Delay

17. Updated Time Table 26/4: learning theoretical material 3/5: understanding previous experiment 10/5: designing the new experiments Mid presentation 5/7: part list 19/7: designing printed circuits Experiment booklet –2/8 theoretical part –16/8 practical part

18. Future Objectives Writing the part list Finishing designing and printing all of the experiments Writing the experiment booklet
