A photodetector integrated circuit (PDIC) capable of being used with at least two different types of optical discs includes a photodetector (PD) array and a switch matrix. The PD array includes a center channel PD and a side channel PD electrically isolated from the center channel PD. The switch matrix, which includes a plurality of inputs and a plurality of outputs, can be selectively configured in a plurality of different switch configurations. The side channel PD includes a plurality of electrically isolated PD sections. Each electrically isolated PD section of the side channel PD is adapted to detect light and provide an electrical output signal, indicative of the light detected by the PD section, to a different one of the inputs of the switch matrix. The switch matrix is adapted to combine the electrical output signals provided by the electrically isolated PD sections of the side channel PD in a plurality of different manners, in dependence on which of the plurality of different switch configurations is selected.
