All the signal lines are available on associated test points. The module PWRDWN, TXDIS, and MODDESEL lines may be manually controlled by switches S1, S3, and S5. 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. Software Control The FDB-1022 evaluation board is supplied with software and a DB-25 cable for communication with a PC parallel port. This cable allows direct communication between the PC and the module via the 2-wire serial bus on pins SCL and SDA. XFP modules respond to 2-wire serial bus address A0h. Additionally, various evaluation board functions may be addressed on other I2C addresses. Contact Finisar for details on these functions. As supplied, the FDB-1022 is configured to accept a 10Gb/s differential REFCLK signal at SMA connectors J5/J6. An onboard divider converts this signal to the 1/64 rate REFCLK the XFP transceiver module requires. Alternatively, the board may be configured to allow a direct connection of a 1/64 clock through SMA connectors J16 and J21.
