Reception apparatus, communication system, and clock recovery method

Abstract

According to one embodiment, there is provided a reception apparatus including a preamplifier and a clock recovery circuit. The preamplifier is configured to receive data through a wired transmission path. The clock recovery circuit is configured to sample a value during an edge period and a value during a data period, which are in data received from the preamplifier, by using a reference clock, to execute a phase adjustment to the reference clock with respect to a transition timing of a signal level of the data in a case sampling results is satisfied a particular condition concerning a transition of the signal level of the data, and to execute no phase adjustment to the reference clock with respect to the transition timing of the signal level of the data in a case the sampling results is not satisfied the particular condition.
