Notes:
1. 10/100/1000 BASE-T operation requires the host system to have an SGMII interface with no clocks, and
the module will operate as 1000BASE-T only when the host system use SERDES interface.

EEPROM Information
The SFP MSA defines a 256-byte memory map in EEPROM describing the transceiver’s capabilities,
standard interfaces, manufacturer, and other information, which is accessible over a 2 wire serial interface at
the 8-bit address 1010000X (A0h). The memory contents refer to Table 6. The physical IC can also be
accessed via 2-wire serial bus at address ACh, please refer the related document of Fiberxon 1000BASE-T

3. MOD-DEF 0,1,2 are the module definition pins. They should be pulled up with a 4.7k~10kΩ resistor on
the host board. The pull-up voltage shall be VccT or VccR.
MOD-DEF 0 is driven high immediately on PHY power-up or reset. It goes low after the PHY startup
sequence has completed. The minimum time this signal is high before being drive low is 10ms. Low level
indicates that the module is present.
MOD-DEF 1 is the clock line of two wire serial interface for serial ID
MOD-DEF 2 is the data line of two wire serial interface for serial ID
4. LOS is not used and tied to ground within the module.
5. These are the differential receiver output. They are internally AC-coupled 100Ω differential lines which
should be terminated with 100Ω (differential) at the user SERDES.
6. These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential
termination inside the module.
