EEPROM Description

      The SFP serial ID provides access to sophisticated identification information that describes thetransceiver's capabilities, standard interfaces, manufacturer, and other information. The serialinterface uses the 2-wire serial CMOS E'PROM protocol defined for the ATMELAT24C01A/02/04 family of components.
      When the serial protocol is activated, the host generates the serial clock signal (SCL, Mod Def1). The positive edge clocks data into those segments of the E²PROM that are notwrite-protected within the SFP transceiver. The negative edge clocks data from the SFptransceiver.
      The serial data signal (SDA, Mod Def 2) is bi-directional for serial data transfer. The host usesSDA in conjunction with SCL to mark the start and end of serial protocol activation. Thememories are organized as a series of 8-bit data words that can be addressed individually orsequentially.

Monitoring Interface

      The interface is an extension of the serial ID interface defined in the SFP MSA specificationThe specifications define a 256 byte memory map in E~PROM which is accessible over a 2wire serial interface at the 8 bit address 1010000X (A0h). The digital diagnostic monitoringinterface makes use of the 8 bit address 1010001X (A2h), so the originally defined serial IDmemory map remains unchanged. The interface is backward compatible with both the GBICspecification and the SFP MSA. 

Note requirements:

1. TX Fault is an open collector output, which should be pulled up with a 4.7K~10KI resistoron the host board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation:logic 1 indicates a laser fault of some kind. In the low state, the output will be pulled to lessthan 0.8V.
2. TX Disable is an input that is used to shut down the transmitter optical output. It is pulled upwithin the module with a 4.7K~10K resistor. Its states are:Low (0_0.8V): Transmitter on
(>0.8V,<2.0V): Undefined
High (2.0~3.465V): Transmitter Disabled
Open: Transmitter Disabled.
3. MOD-DEF 0,1,2 are the module definition pins. They should be pulled up with a4.7K~10K resistor on the host board. The pull-up voltage shall be VccT or VccR.MOD-DEF 0 is grounded by the module to indicate that the module is presentMOD-DEF 1 is the clock line of two wire serial interface for serial IDMOD-DEF 2 is the data line of two wire serial interface for serial ID.4. LOS is an open collector output, which should be pulled up with a 4.7K~10K resistor onthe host board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation:logic 1 indicates loss of signal. In the low state, the output will be pulled to less than 0.8V.5. These are the differential receiver outputs. They are AC coupled 1001 differential lineswhich should be terminated with 1009 (differential) at the user SERDES.6. These are the differential transmitter inputs. They are AC-coupled, differential lines with1002 differential termination inside the module.
