FinisarFDB-1022Entwicklungssätze und Werkzeuge

FDB-1022 Evaluation Board is a convenient and powerful vehicle for testing and evaluating the new 10 Gigabit/s XFP optical transceivers.
 
The board consists of a single XFP connector and cage, high quality transmission lines and connectors for the serial data signals, connections for reference clock inputs, all low speed status and control lines, and the 2-wire serial management interface. All pin connections are compliant with the XFP MSA Rev 1.0 Standard.

For convenience, the FDB-1022 contains onboard switching and linear power supplies to provide all three required module power supplies (1.8V, 3.3V and 5.0V) from a single external +12V connection. The outputs of each onboard supply are factory set, and may be switched off and on using S2. These supplies can be adjusted and monitored (both voltage and current) using the supplied evaluation board software. By removing jumpers J8, J11 and/or J12, the on-board supplies may be disconnected from the module and external supplies be connected at test points labeled 1.8/3.3/5.0V MOD PIN. These test points may be used to confirm the voltage at the module supply pins when using the on-board supplies. As a further convenience, a small fan is provided for cooling the module. This fan may be disabled by removing its power connector from jumper J10.

 
The software included with the board provides a simple windows-based GUI and allows control and monitoring of the power supply and status functions of the evaluation board itself. Future versions of the software will allow monitoring of the Serial ID, digital diagnostics and status information available in Finisar’s XFP transceivers.

• The Finisar FDB-1022 evaluation board requires a +12V ±10% power supply at J14. Input signals to the TX+ and TX- connectors should have an amplitude between 140mV and 700mV differential peak-to-peak (70mV to 350mV single-ended). Output signals on the RX+ and RX-connectors will have amplitudes between 180mV and 640mV single-ended.
• A 10Gb/s REFCLK may be supplied at J5/J6. The onboard divider requires a signal amplitude of 200–1000 mV differential p-p (100-500mV S.E.). If a direct REFCLK connection is made, a signal of 640 – 1600 mV differential p-p (320 – 800 mV S.E.) is required.
