Oscillator apparatus and oscillation method

Abstract

The present technology relates to an oscillation apparatus and an oscillation method allowing a variation in a frequency of a clock signal to fall within a predetermined range without using a reference clock signal. An oscillation apparatus according to the first aspect of the present technology includes an oscillation section oscillating a clock signal, an adjustment section changing a parameter of a constituent element constituting the oscillation section to thereby adjust a frequency of the clock signal, and a calibration control section controlling the adjustment section to perform frequency calibration of the oscillation section in a case in which a variation in a frequency of the clock signal oscillated by the oscillation section falls within a second range exceeding a first range permitted in an application of the clock signal. The present technology is applicable to a system that permits a variation within a certain range to a transmission rate or a system that permits a variation in a sampling (clock) frequency within a certain range to a predetermined transmission rate.
