Abstract:
1. A method of synchronizing a first clock in a first multiphase data converter with a second clock in a second multi-phase data converter, the method comprising: connecting the first clock to the second clock using a first symmetric link, connecting the second clock to the first clock using a second link, sending a pulse along the symmetric link when the first clock reaches a predetermined condition, sending a pulse along the symmetric link when the second clock reaches a predetermined condition, capturing the state of the first clock as a first time offset when the pulse from the second clock arrives on the symmetric link, capturing the state of the second clock as a second time offset when the pulse from the first clock arrives on the symmetric link, transferring the second time offset from the second clock to the first clock via the second link, and computing an offset correction between the first clock and the second clock from the first time offset and the second time offset.
