Figure 17. Recommended CC-Link application circuit.
Implementing CC-Link with the HCPL-772X/072X
CC-Link (Control and Communication Link) is developed
to merge control and information in the low-level net-
work (field network) by PCs, thereby making the mul-
tivendor environment a reality. It has data control and
message-exchange function, as well as bit control func-
tion, and operates at the speed up to 10 Mbps.

Power Supplies and Bypassing
The recommended CC-Link circuit is shown in Figure
17. Since the HCPL-772X/072X are fully compatible with
CMOS logic level signals, the optocoupler is connected
directly to the transceiver. Two bypass capacitors (with
values between 0.01 μF and 0.1 μF) are required and
should be located as close as possible to the input and
output power supply pins of the HCPL-772X/072X. For
each capacitor, the total lead length between both ends
of capacitor and the power supply pins should not ex-
ceed
cause of the high speed digital nature of the signals in-
side the optocoupler.
