Abstract
Integrated circuit and process for aligning a first signal with a second signal. The integrated circuit includes a single latch, a switch control circuit coupled to an input of the single latch to align an edge of the first signal with an edge of the second signal, and a second switch control circuit coupled to the output of the single latch to produce a 50% duty cycle output.
Claims29
An integrated circuit capable of aligning a first signal with a second signal, the integrated circuit comprising:
- a single latch;
- a switch control circuit coupled to an input of the single latch to align an edge of the first signal with an edge of the second signal;
- and
- a second switch control circuit coupled to the output of the single latch to produce a 50% duty cycle output.
A process for aligning a first signal with a second signal, comprising:
- applying the second signal to an input of a single switch shaping latch;
- and
- aligning an edge of the second signal with an edge of the first signal,
- wherein an output of the single switch shaping latch has a 50% duty cycle output.
A clock signal synchronization device comprising:
- a shaping latch composed of a single switch.
A process for synchronizing a first clock signal with a second clock signal, in which edges of the second clock signal are not aligned with edges of the first clock signal, the process comprising:
- aligning the edges of the second clock signal with the edges of the first clock signal through a shaping latch composed of a single switch.
