Digital Supply
3-2
3.1
Digital Supply
The evaluation board digital 5-V power supply can be the same power supply
for the CIB or user
’
s control board. To prevent ground loops of the digital power
supply, a BNX filter (FL1) is placed on the digital power input (see Figure 3-1).
The zener diode (CR1) protects against over-voltage as well as reverse
voltage on the digital input.

1.Digital Power Input
If the user furnishes different power supplies for the CIB board and for the
digital portion of the evaluation board, the high frequency inductor at FL5 will
help to reduce ground noise (see Figure 3-2).

2.Secondary Digital Filter
3.2
Analog Supply
The analog power supply is more critical then the digital. The input DSS306
filters are placed on both analog power input supply lines. The zener diodes
on the input lines protect against overvoltage or reverse voltage. Another
inductor is placed on the input line to the analog ground. If the same power
supply is used for the digital and analog circuits, the BL02 inductor (FL3)
combined with the BNX filter (FL1) on the digital input, will break and separate
the analog and digital grounds (see Figure 3-3).
