Notes:

1. Clock tolerance is +/- 50 ppm

2. By default, the FCLF-8520/8521-3 is a full duplex device in preferred master mode

3. Automatic crossover detection is enabled. External crossover cable is not required

4. 10/100/1000 BASE-T operation requires the host system to have an SGMII interface

with no clocks, and the module PHY to be configured per Application Note AN-2036.

With a SERDES that does not support SGMII, the module will operate at 1000BASE-T

only.

 

 

 

VI. Environmental Specifications

VII. Serial Communication Protocol

 

All Finisar SFPs support the 2-wire serial communication protocol outlined in the SFP

MSA

For details on interfacing with the E

“AT24C01A/02/04/08/16 2-Wire Serial CMOS E

 

The 1000BASE-T physical layer IC can also be accessed via the 2-wire serial bus at

address ACh. For details interfacing with the PHY IC, see Marvell data sheet titled

“Alaska Ultra 88E1111 Integrated Gigabit Ethernet Transceiver”

number MV-S100649-00).
