Temperature Reading Compensation
The sensed temperature by the MIC3002 can be
temperature compensated and converted to the optical
module case temperature to be monitored or used for
modulation and other parameters (L.U.T.s). There are 39
entries (bytes) at address A6: 96-134 (60-86h) where the
OEM can enter the temperature difference between the
chip (sensed) temperature and the measured module
case temperature over the operating temperature range.
Table 7 shows the correspondence between the entries
and temperature intervals.
The resolution of this table is 0.5oC/bit. The number
entered should be twice the temperature difference. For
example if the chip-case temperature difference is 5oC,
the value to be entered should be 2x5=10.
