Function Tables
Table 3A. Control Input Function Table
After nCLK_EN switches, the clock outputs are disabled or enabled following a falling input clock edge as shown in Figure 1. In the
active mode, the state of the outputs are a function of the CLK0, nCLK0 and CLK1, nCLK1 inputs as described in Table 3B.
