  • Patent number: 9531390
    Abstract: An integrated circuit includes first and second data channel circuits and first and second inductor-capacitor (LC) tank oscillator circuits. The first data channel circuit generates a first data signal in response to a first clock signal. The second data channel circuit generates a second data signal in response to a second clock signal. The frequencies of the first and second clock signals are substantially the same. The first LC tank oscillator circuit generates a first periodic signal. The first clock signal is generated in response to the first periodic signal. The second LC tank oscillator circuit generates a second periodic signal. The second clock signal is generated in response to the second periodic signal. The first and second LC tank oscillator circuits generate non-overlapping frequency ranges for the first and second periodic signals.
