Claim:
1. A spread spectrum clock (SSC) generator comprising: an SSC modulator for generating a spread spectrum clock signal based on a modified SSC profile, the spread spectrum clock signal comprising a variation of a reference clock signal according to the modified SSC profile; and an SSC profile modifier in communication with the SSC modulator, for receiving an ancillary data and modifying an SSC profile associated with the SSC modulator according to the ancillary data symbol to generate the modified SSC profile, wherein the variation of the reference clock signal of the spread spectrum clock signal is uniquely mapped to the ancillary data symbol via the modified SSC profile, wherein the SSC generator is connected to a transmitter for transmitting a message at a plurality of frequencies according to the spread spectrum clock signal, and the ancillary data symbol is encoded within a sequence of the frequencies of the plurality of frequencies used for transmitting the message.
