Functional region for analog elements has ground strips for this region on two inner layers of printed circuit board (second and (N-1)-th). Analog power supply strip is located in one of inner conducting layer which is adjacent to second or (N-1)-th layer. In all M-1 functional regions for digital elements, one of inner conducting layers of printed circuit board, which is adjacent to first or N-th outer conducting layer, contains separate ground strip of respective functional regions. One of inner conducting layers of printed circuit board, which is split by at least one conducting layer from layer with ground strips of functional regions of digital elements contains separate isolated strips for digital power supply of these regions.
