* Each DCKPH input pin of all chips should be connected to the same voltage level.
* DCKPH input pins of odd stages (Chip01, Chip03…) and even stages (Chip02,
8x3-CHANNEL CONSTANT CURRENT LED DRIVERS
Figure 12 shows that all DCKPH pins are connected to VSS.
Chip04…) should be connected to different voltage level. Figure 13 shows that
CLKPH pins of odd stages are connected to VSS, and CLKPH pins of even stages
are connected to VDD.
