Application Diagram
a) DCK LTH and GCK signals: Global Connected
* Each DCKPH input pin of all chips should be connected to the same voltage level.
Figure 12 shows that all DCKPH pins are connected to VSS.

Figure 12. DCK LTH and GCK signals: Global Connected
b) DCK LTH and GCK signals: Cascade Connected
* DCKPH input pins of odd stages (Chip01, Chip03…) and even stages (Chip02,
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.
