Patent ID: 7876857

Claim:
A data receiving apparatus that receives serial data of a first signal line and a second line, the data receiving apparatus comprising: a comparator that uses the first signal line and the second signal line for a differential input; a trigger generation section that generates a trigger signal before an output of the comparator switches, when a first signal and a second change from out-of phase to in-phase; a storage section that retrieves, by means of the trigger signal, and stores the output before the comparator switches, when the first signal and the second signal change from out-of-phase to in-phase; and a selection that, when a first signal of the first signal line and a second signal of the second signal line are out-of-phase with each other, selects the output of the comparator and outputs the output as received data, and, when the first signal and the second signal change from out-of-phase to in-phase, switches from the output of the comparator to a value stored in the storage section and outputs the value as received data.
