ABSTRACT:
Synchronizing multiple-phase data converters by exchanging terminal count pulses via a bidirectional link. Multiple-phase data converters such as analog to digital converters (ADCs) or digital to analog converters (DACs) are synchronized to operate at the same phase by exchanging terminal count (TC) pulses and capturing counter state, representing a time offset from TC. Time offset and the symmetrical delay introduced by the link are used to solve for the delay introduced by the link and the off-set between devices. The offset information is used to align the devices. The process may be repeated to correct for drift.
