Carrier generator, radio frequency interconnect including the carrier generator and method of using

A radio frequency interconnect (RFI) comprising:

• a transmitter configured to transmit data on a plurality of first carrier signals;
• and
• a receiver configured to receive the data from the transmitter, wherein the receiver comprises a carrier generator comprising:
• a phase accumulator configured to generate a phase reference signal based on a frequency command word (FCW) signal;
• a time to digital converter (TDC) configured to generate a feedback signal based on a divided signal;
• a loop filter configured to generate a filtered command signal based on the phase reference signal and the feedback signal;
• and
• a plurality of tuning arrangements configured to generate a plurality of second carrier signals corresponding to the plurality of first carrier signals, wherein each tuning arrangement of the plurality of tuning arrangements comprises a digital controlled oscillator (DCO) configured to receive the filtered command signal,
• wherein the divided signal is based on an adjustment signal output by a first DCO of a first tuning arrangement of the plurality of tuning arrangements.

A method of generating a plurality of carrier signals, the method comprising:

• generating, using a phase circuit, a phase circuit output signal based on a frequency reference signal;
• generating a feedback signal using a divider;
• generating a command signal based on the phase circuit output signal and the feedback signal;
• receiving the command signal at a plurality of tuning arrangements, wherein receiving the command signal comprises an oscillator in each tuning arrangement of the plurality of tuning arrangements receiving the command signal and outputting an adjustment signal;
• and
• generating, with the plurality of tuning arrangements, a plurality of carrier signals, each carrier signal of the plurality of carrier signals corresponding to a respective adjustment signal, wherein generating the feedback signal comprises the divider applying a division integer to a first carrier signal of the plurality of carrier signals.
