Abstract

See full text

One embodiment relates to a multiple-channel serializer circuit that includes a plurality of one-channel serializers. A one-channel serializer of the plurality of one-channel serializes includes a local 2× frequency clock generator with a non-divider structure. Other embodiments relate to methods of using a non-divider circuit to generate a local 2× frequency clock signal in a one-channel serializer of a multiple-channel serializer. Another embodiment relates to a local 2× frequency clock generator circuit with a non-divider structure. The local 2× frequency clock generator circuit includes a first circuit path which is selected by multiplexers for a first serialization ratio and may also include a second circuit path which is selected by the multiplexers for a second serialization ratio. Other embodiments and features are also disclosed.
