Set MOD (Modulation) for FF (Feed Forward) setting.
Degraded LD characteristic is compensated by BIAS
only. Initial value of BIAS FB (FeedBack) can be
programmed in response to a start-up temperature
(Set by RE_APC_INIT_SET).
Set BIAS for FF setting.
Degraded LD is compensated by MOD only. Initial
value of MOD FB can be programmed in response to
a start-up temperature (Set by RE_APC_INIT_SET).
Set both BIAS and MOD for FF setting. No
compensation of degraded LD is made.
Set both BIAS and MOD for FF setting.
Compensation of degraded LD is made by the MOD.
Set both BIAS and MOD for FF setting.
Compensation of degraded LD is made by BIAS.
Compensation of degraded LD is made in accordance
with the dividing coefficient for BIAS and MOD initial
value of FB can be programmed in response to a
MOD outputs a current that is sum of the divided FB
current and the FF setting current.
BIAS outputs a current that is proportional to the
divided FB current. Initial value of BIAS FB can be
programmed in response to a start-up temperature
(Set be RE_APC_INIT_SET).
BIAS outputs a current that is sum of the divided FB
current and the FF setting current.
MOD outputs a current that is proportional to the
divided FB current. APC_FB initial value setting is
prohibited in this setting [*].
Both in BIAS and MOD, a current that is
proportional to the divided FB is added to the FF
setting current and compensation of degraded LD is
made by the FB current.
