Q.14.1
When +5 V is supplied to the V
A.14.1
The +5 V power supply is used only to supply withstand voltage of 5 V to the PCI bus interface and does not affect
the internal operation. Therefore, even if +5 V is supplied to the V
the normal current consumption (refer to the µ µ µ µ PD98409 Data Sheet) × 3.3 V.

Q.14.2
Can a 5 V device be directly connected to the UTOPIA interface? At that time, does the handling of the V
influence this connection?
A.14.2
A 5 V device can be directly connected to the UTOPIA Interface. The power supplied to the V
has nothing to do with the device. Supply +5 V to the V
