Patent 9531390 was granted and assigned to Altera on December, 2016 by the United States Patent and Trademark Office.
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.
