Capstone Design UpdateWeek 9ECE 4006 – Group 1 Presentation by: Ragad Amin Al-Huq 27 March, 2003
Progress Summary • Completed and turned in the first report • Built the circuit for the regular design of the transceiver module • Tested the receiver and transmitter • Started to solder in the parts for the aggressive design
Oops!! might have blown up the PD!! • Got confused between the cathode and the anode • Grounded the cathode pin of the photodetector • Remedy: scratched off the connection between ground and cathode pin, reversed the PD on the board
Maybe not! PRBS7 K28.5
However… • When constructing the board initially, we soldered in the common cathode VCSEL with the anode going to ground. • After we fixed this, no signal was transmitting
Upcoming Tasks • Continue with the testing
