Plane Partitioned for V
Thick V
Because of board constraints, you might not be able to partition a V
island. Instead, run a thick trace from the power supply to each V
The traces should be at least 20 mils thick.
In each of these three cases, you should filter each V
decoupling circuit shown in
high impedance at frequencies of 50 MHz or higher and a 10- F tantalum
parallel capacitor where the power enters the board. Decouple each V
pin with a 0.1- F and 0.001- F parallel combination of ceramic capacitors
located as close as possible to the Stratix or Stratix GX device. You can
connect the GNDA pins directly to the same ground plane as the device’s
digital ground.
