Digital Diagnostic Memory Map

The transceivers provide serial ID memory contents and diagnostic information about the present operating conditions by the 2-wire serial interface (SCL, SDA).

The diagnostic information with internal calibration or external calibration all are implemented, including received power monitoring, transmitted power monitoring, bias current monitoring, supply voltage monitoring and temperature monitoring.

The digital diagnostic memory map specific data field defines as following.

Notes:

Plug Seq.: Pin engagement sequence during hot plugging.

1) TX Faultisan open collector output, which should be pulled up with a 4.7k~10kΩ resistor on 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 less than 0.8V.

2) TX Disable is an input that is used to shut down the transmitter optical output. It is pull e dup within the module with a 4.7k~10kΩ resistor. Its states are:

Low (0 to 0.8V): Transmitteron

(>0.8V, < 2.0V): Undefined

High (2.0 to 3.465V): TransmitterDisabled

Open: TransmitterDisabled

3) Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7k~10kΩ resistor onthe host board. The pull-up voltage shall be Vcc Tor VccR.

Mod-Def 0 is ground edgy the module to indicate 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 an open collector output, which should be pulled up with a 4.7k~10kΩ resistor. Pull up voltage between 2.0V and Vcc 0.3V. Logic 1 indicates loss of signal; Logic 0 indicates normal operation. In the low state, the output will be pulled to less than 0.8V.

5) RD-/ : These are the differential receiver outputs. They are internally AC-coupled 100 differential line swhich should be terminated with 100Ω (differential) attheuser SERDES.

6) TD-/ : These are the differential transmitter in puts. They are internally AC-coupled, differential line swith 100Ω differentialterminationinsidethe module.
