Table 3a. Control Input Function Table
After CLK_EN switches, the clock outputs are disabled or enabled following
a rising and falling input clock edge as shown in figure1. In the active mode, the state
of the outputs are a function of the CLK0 and CLK1 inputs as described in Table 3b.
Table 3b. Clock Input Function Table
Note:
*PI6C41204 and PI6C41204A have four differential outputs. Q0 through Q3 and nQ0 through nQ3.
PI6C41202 has two differential outputs. Q0 through Q1 and nQ0 through nQ1.
