VII. Serial Communication Protocol
All Finisar GBICs are ‘Module Definition “4”’ and support the 2-wire serial
communication protocol outlined in the GBIC Specification
1. These GBICs use an Atmel
AT24C01A 128 byte E
2PROM with an address of A0h. For details on interfacing with
the E
2PROM, see the Atmel data sheet titled “AT24C01A/02/04/08/16 2-Wire Serial
CMOS E
2PROM.”5
The 1000BASE-T physical layer IC can also be accessed via the 2-wire serial bus at
address A4h. For details interfacing with the PHY IC, see Marvell data sheet titled
“Alaska Ultra 88E1011/88E1001S Integrated Gigabit Ethernet Transceiver”
6 (Marvell
document number MV-5100281-00).
