• Voltage above +45 V may damage the optical
coupler.
• The output connection is different to the AVT Dolphin
series to achieve higher output swing.
• Depending on the voltage applied at OutVCC and the
type of input which you want to drive, it may be neces-
sary to switch an external resistor in series between
GPOut1...4 and ground. See
Figure 34: Output schemat-
ics with external resistors R (pin no. from camera I/O
connector) (PIKE)
on page 57.
• Typical delay is not more than 40 µs.
