Abstract
A multi-instance time-interleaving (TI) system and method of operation therefor. The system includes a plurality of TI devices, each with a plurality of clock generation units (CGUs) coupled to an interleaver network. Within each TI device, the plurality of CGUs provides a plurality of clock signals needed by the interleaver network. A phase detector device is coupled to the plurality of TI devices and configured to determine any phase differences between the clock signals of a designated reference TI device and the corresponding clock signals of each other TI device. To determine the phase differences, the phase detector can use a logic comparator configuration, a time-to-digital converter (TDC) configuration, or an auto-correlation configuration. The phases of the clock signals of each other TI device can be aligned to the reference TI device using internal phase control, retimers, delay cells, finite state machines, or the like.
