TRIPLE 155 MHz LASER SWITCH
Rev A4, Page 6/8
CURRENT CONTROL
The voltage at pins CI1/2/B sets the current in pins
LDK1/2/B. Figures 2 and 3 show the temperature de-
pendency of the current in a single LDKx output versus
the voltage at CIx for a
typical
device. Figures 4 and
vices at 27 °C temperature.
Figure 2: I(LDK1/2) vs. V(CI1/2) at VDD = 5 V
Figure 3: I(LDK1/2) vs. V(CI1/2) at VDD = 3.3 V
Figure 4: I(LDKx) vs. V(CIx) at VDD = 5 V
Figure 5: I(LDKx) vs. V(CIx) at VDD = 3.3 V
DEMO BOARD
iC-HB comes with a demo board for test purpose. Figures 6 and 7 show both the schematic and the component
side of the demo board.
