Digital Diagnostic Memory Map (Compliant with SFF-8472)
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 (For further information, please refer to
SFF-8472).
