Clock structure with calibration circuitry

摘要

An integrated circuit includes a clock circuit that may be used to provide clock signals to multiple input-output circuits. The integrated circuit may also include different clock structures. As an example, one of the clock structures may have multiple clock paths of substantially equal lengths while another clock structure may have a fly-by clock path. The multiple clock paths may be used to convey a subset of the clock signals to the input-output circuits. Similarly, the fly-by clock path may be used to transmit a second subset of the clock signals to the input-output circuits.

1. An integrated circuit comprising:
a clock circuit that provides a plurality of clock signals; a plurality of input-output circuits; a first clock structure having a plurality of clock paths of substantially equal lengths, wherein the plurality of clock paths conveys a first subset of the plurality of clock signals to the plurality of input-output circuits; and a second clock structure having a fly-by clock path, wherein the fly-by clock path transmits a second subset of the plurality of clock signals to the plurality of input-output circuits.
