Methods include receiving a pair of input clock signals; utilizing a stratum clock state machine to control a multiplexer; utilizing the multiplexer to switch an input of a main clock between each of the pair of input clock signals; inducing a phase build-out activity; and transmitting an output clock signal. Prints when subjected to face-to-face stacking under these conditions tend to stick and are difficult to separate without damage. Hence cables may be of lighter construction than that required for conventional laying procedures. The flexible circuit board electrically connects the radiation detection panel with the circuit board, and on which an integrated circuit is mounted.
