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

摘要

A carrier generator includes a phase accumulator configured to receive a frequency command word (FCW) signal. The carrier generator includes an adder connected to the phase accumulator; and a loop filter configured to receive an output of the adder. The carrier generator includes a plurality of tuning arrangements, each tuning arrangement is configured to receive an output of the loop filter. Each tuning arrangement includes an electronic oscillator configured to receive the output of the loop filter. Each tuning arrangement includes a voltage controlled delay line (VCDL) configured to receive an output of the electronic oscillator, and to provide a tuning arrangement output. Each tuning arrangement includes a phase detector configured to receive a corresponding recovered clock signal and a feedback from a corresponding tuning arrangement output. Each tuning arrangement includes a counter configured to receive an output of the phase detector and to provide an output to the VCDL.
