Parameter Interpretation

The parameters listed in the following partly represent the characteristics of the C164CM

and partly its demands on the system. To aid in interpreting the parameters right, when

evaluating them for a design, they are marked in column “Symbol”:

CC (Controller Characteristics):

The logic of the C164CM will provide signals with the respective characteristics.

SR (System Requirement):

The external system must provide signals with the respective characteristics to the

C164CM.
