Finisar Product Specification 1000BASE-T Copper GBIC Transceivers FCL-8520/8521-3 Product Features • • • • • • • Up to 1.25Gb/s bi-directional data links RoHS compliant and Lead Free Extended operating temperature range (0°C to +75°C) Hot-pluggable Fully metallic enclosure for low EMI Low power (1.5W typical) Access to physical layer IC via 2wire serial bus Applications • 1.25 Gigabit Ethernet over Cat 5 cable Finisar’s FCL-8520/8521-3 1000BASE-T Copper GBIC transceivers are based on the GBIC Specification Revision 5.51. They are compatible with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE Std 802.3z2 and IEEE Std 802.3ab3. The FCL-8520-3 uses the GBIC’s RX_LOS pin for link indication, and 1000BASE-X auto-negotiation must be disabled on the host system. The FCL-8521-3 is compatible with 1000BASE-X auto-negotiation, but does not have a link indication feature (RX_LOS is internally grounded). See AN-2032, “Commonly Asked Questions Regarding Auto-negotiation on Finisar’s 1000BASE-T GBICs”4, for a more complete explanation on the differences between the two models.

Caution: Power consumption and inrush current are higher than the specified values in the GBIC Specification Rev 5.51. III. Low-Speed Signals RX_LOS is a TTL signals as described in Table 3 and 4. MOD_DEF(1) (SCL) and MOD_DEF(2) (SDA), are open drain CMOS signals (see section VII, “Serial Communication Protocol”). Both MOD_DEF(1) and MOD_DEF(2) must be pulled up to host_Vcc.

Serial Communication Protocol All Finisar GBICs are ‘Module Definition “4”’ and support the 2-wire serial communication protocol outlined in the GBIC Specification1. These GBICs use an Atmel AT24C01A 128 byte E2PROM with an address of A0h. For details on interfacing with the E2PROM, see the Atmel data sheet titled “AT24C01A/02/04/08/16 2-Wire Serial CMOS E2PROM.”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).
