10 Gbit/s Pattern Generator
I designed this board for Princeton Optronics when they could not afford to buy a $200K 10Gbit/sec pattern generator. The unit utilizes a GIGA (now Intel) GD16555B MUX chip to generate a selectable 32 bit pattern. The output bit rate and level are adjustable. The board has six layers with controlled impedances on all signal layers. Worked very well for testing the "proof of concept" optical transmitters and receivers.
Total cost of parts and fab was about $1.5k
