Notes
1.
Remarks to the supply current:
a) The value for I
CC
does not include the modulation and bias currents through pins LA, LAQ and BIAS.
b) Typical value for I
CC
refers to, but does not include, I
MOD
= 30 mA and I
BIAS
= 45 mA.
c) The maximum value of I
CC
refers to, but does not include, I
MOD
= 60 mA and I
BIAS
= 90 mA.
Remarks to the power dissipation:
a) The value for P
tot
includes the modulation and bias currents through pins LA, LAQ and BIAS.
b) The typical value for P
tot
is the on-chip dissipation with I
MOD
= 30 mA and V
LA
= V
LAQ
= 2 V, I
BIAS
= 45 mA and
V
BIAS
= 1 V and typical process parameters.
c) The maximum value for P
tot
is the on-chip dissipation with I
MOD
= 60 mA and V
LA
= V
LAQ
= 2 V, I
BIAS
= 90 mA and
V
BIAS
= 1 V and worst case process parameters.
The minimum value of the capacitance on pin MONIN is required to prevent instability.
The reference currents can be set using a resistor connected between pins ONE or ZERO and V
CC
(see Section “Automatic laser control”). The corresponding ZERO level MPD current range is from 24 to 260
μ
A.
The ONE level MPD current range is from 96 to 1040
μ
A.
The specified transconductance is the ratio between the modulation current at pins LA or LAQ and the voltage at
pin TONE, under small signal conditions.
