Abstract: Efficient synchronization techniques that support multiple reference clocks in an EQAM device. Consider a plurality of different modulators in the EQAM device receiving data from a corresponding plurality of different sources having corresponding different timing references (i.e., different source reference clocks). To accommodate this, the modulators all operate using a common system clock, and each modulator is provided with a phase synchronizer. The phase synchronizer synchronizes the modulated symbol phases to the corresponding reference clock.
