The CY9266 evaluation board was provided to allow the user to fully characterize the CY7B923/CY7B933 transmitter and receiver. It was available in four 'flavors':
CY9266-F = optical fiber
CY9266-P = plastic optical fiber
CY9266-T = shielded twisted pair/twinax
CY9266-C = coaxial cable
The CY9266 HOTLink Evaluation Board User's Guide is the complete guide to setting up and testing the various evaluation boards. It also includes schematics and layout information for reference.
Since the Evaluation Board is Obsolete. If customer wants to design the evaluation board, they can use the gerber files attached with this KB Article for CY9266-F & CY9266-C.
