  • Phase synchronization of modulation or demodulation for QAM-based multiband TSV-link
    Patent number: 9491028
    Abstract: A chip-to-chip communications circuit which is particularly well-suited for short range wired RF communication from one integrated circuit (chip) to another is presented. The circuits preferably utilize multi-frequency quadrature amplitude modulation (QAM) mechanisms for converting digital data bits from a parallel form into a serial analog stream for communication over a chip I/O connection. During a phase calibration cycle, a phase adjustment controller in the transmitter interoperates with a phase adjustment controller in the receiver, to adjust a phase locked-loop (PLL) circuit to correct for the phase delay arising in response to signal propagation between transmitter and receiver.
