Abstract
A data reception apparatus includes: an oscillation circuit that multiplies or divides an oscillation signal from a CR oscillator based on a cycle setting value, and outputs a clock signal corresponding to the multiplied or divided oscillation signal; a temperature detector; a memory; a clock cycle setting element that reads the cycle setting value corresponding to the temperature from the memory, and inputs the cycle setting value into the oscillation circuit; a receiver that receives a data signal defined by the clock signal; a measurement element that measures a unit bit length of the data signal by counting the clock signal; and a correction element that corrects the cycle setting value based on a count value of the clock signal and a reference count value of a reference cycle corresponding to the unit bit length, and rewrites the cycle setting value with the corrected cycle setting value.
