SPDIF is phase modulated. It is not amplitude modulated. It is a purely digital signal, transmitted at two voltage levels. SPDIF uses a variation of Manchester coding. For each bit time there will be either one or two signal transitions. This doubles the analog bandwidth on the cable, but this makes it easy to recover timing information and ensures that there will be no net DC voltage on the cable, regardless of the data being transmitted.
