Z
is divided between Z
programmed to 100 mA, a typical Z
internal resistor. This corresponds to a voltage swing of 2 V on the real application load.
L(LA)
VTEMP
is the external load on pin LA. The voltage on pin MODIN programmes the modulation current I
= 1.31 + TC
CCO
minus the laser diode voltage which results in a lower total power dissipation.
