Abstract
A device may include an oscillator to generate a clock signal based on first and second control signals. The oscillator may include a first buffer stage a second buffer stage. The first buffer stage may output a first signal that is based on an output of the second buffer stage and the first control signal. The second buffer stage may output the clock signal. The clock signal may be based on the first signal and the second control signal.
Claims20
A device comprising:
- an oscillator to generate a first clock signal based on a first control signal and a second control signal,
- the oscillator comprising:
- a first buffer stage, and
- a second buffer stage,
- the first buffer stage to:
- output a signal that is based on an output of the second buffer stage and the first control signal,
- the second buffer stage to:
- output the first clock signal,
- the first clock signal being based on the first signal, output by the first buffer stage, and the second control signal;
- and
- one or more components to:
- receive a second clock signal that indicates data edges of a data stream, and
- generate the first control signal and the second control signal based on the second clock signal.

A system comprising:
- a clock generation component to generate a first clock signal based on a first control signal and a second control signal,
- the clock generation component comprising:
- a first buffer stage, and
- a second buffer stage,
- the first buffer stage to:
- output a signal that is based on an output of the second buffer stage and the first control signal,
- the second buffer stage to:
- output the first clock signal,
- the first clock signal being based on the signal, output by the first buffer stage, and the second control signal;
- and
- one or more detector components to:
- generate the first control signal and the second control signal based on a second clock signal that indicates data edges of a data stream.
9 more elements
A method, comprising:
- outputting, by a first buffer stage of an oscillator device, a signal that is based on an output of a second buffer stage of the oscillator device and a first control signal;
- receiving, by the second buffer stage, the signal output by the first buffer stage;
- and
- outputting, by the second buffer stage, a first clock signal that is based on:
- the signal output by the first buffer stage, and
- a second control signal that is different from the first control signal,
- the first control signal and the second control signal being generated based on a second clock signal that indicates data edges of a data stream,
- the first clock signal indicating a time at which the data stream is to be sampled.
