ADN2843
Best high frequency board layout techniques including power and ground planes should be used.
To minimize inductance, keep the connections between the ADN2845 and the laser diode as short as possible. Inductances <0.3 nH
are recommended for best performance. Critical bonds are IMODP and V
CC
(Pin 14). Ribbon bonding can be used to reduce
bond inductance. Minimize bond lengths for ADN2845 pads to achieve low inductance.
Place bypass capacitor on laser anode as close to laser as possible.
Bypass capacitors should be placed as close as possible to V
CC
pads.
50 controlled impedance interconnects should be used on the DATA inputs.
Parasitic capacitance on IBIAS_CTRL and IMOD_CTRL interconnects should be less than 100 pF. If decoupling caps are used
on IBIAS_CTRL and IMOD_CTRL, they should be tied to V
CC
rather than GND.
An inductor should be used in the bias current path. A Microwave Components coil 30-1847-GCCAS-01 (48 mil
24 mil) should
be used.
The recommended substrate connection is to GND. However, the performance is not affected by connecting the substrate to V
CC.
