Abstract
A clock and data recovery device associated with a data receiving apparatus, the clock and data recovery device including an oscillator configured to generate a clock signal; and a regulator configured to supply current to the oscillator, the regulator including, a first current source configured to supply a first current to the oscillator, and a second current source configured to supply a second current to the oscillator such that the second current is supplied to the oscillator, after a period of time, to de-emphasize the first current, the period of time being based on the first current.
Claims20
A clock and data recovery device associated with a data receiving apparatus, comprising:
- an oscillator configured to generate a clock signal;
- and
- a regulator configured to supply current to the oscillator, the regulator including,
- a first current source configured to supply a first current to the oscillator, and
- a second current source configured to supply a second current to the oscillator such that the second current is supplied to the oscillator, after a period of time, to de-emphasize the first current, the period of time being based on the first current.
A clock and data recovery device associated with a data receiving apparatus, comprising:
- an oscillator configured to generate a synchronized clock signal, the data receiving apparatus configured to receive incoming data based on the synchronized clock signal;
- a variable capacitor configured to selectively adjust a frequency of the oscillator when the oscillator is operated at a frequency higher than a set frequency;
- and
- a regulator configured to supply current to the oscillator, and to selectively adjust the frequency of the oscillator by adjusting the current supplied to the oscillator when the oscillator is operated at a frequency lower than the set frequency.
