Abstract
The present invention provides a chipset for transferring data through an electromagnetically coupled bus system. The chipset includes a modulator, a matching circuit and a demodulator. The modulator modifies a clock to encode multiple bits in a complementary pair of symbols. The matching circuit modifies the clock signal to generate a complementary pair of reference signals that is transmitted with the complementary symbol pair, and the demodulator decodes a second set of bits from selected properties of a complementary pair of transferred symbols.
