The PLLs for SRTS accept RFCLK deviations of at least + and - 50 ppm. However, in
case of switchover to emergency mode, RFCLK will be used to generate the line clock,
which has to fulfill specifications like "maximum 4.6 ppm deviation under ALL
circumstances". In this case RFCLK accuracy has to be 4.6 ppm.
