In various embodiments, the CDR circuit includes a phase detector that receives an input signal and a output reference clock signal. The phase detector then outputs two signals to charge pump. The output from the charge pump drives an oscillator control voltage up or down depending the current from the charge pump. A lock detector detects whether a lock has occurred by comparing the oscillator control voltage to a predetermined threshold voltage. A lock can occur when the circuit has settled into a frequency substantially near the frequency of the input signal and the oscillator control voltage is substantially near the threshold voltage. A controller circuit can control a sweeping of an available frequency range by the circuit until a lock occurs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Clock and data recovery circuitry with asymmetrical charge pump","description":"Introduced here are techniques for implementing a clock and data recovery circuit with improved tendencies, such a pull up and/or pull down tendencies.
