Receiver circuit

摘要

In a receiver circuit, a binary signal is generated based on a signal level of a received signal that has been received via a transmission line from a driver of a transmitter circuit. Then, a first stable state and a second stable state are detected based on a reference signal whose signal level changes in accordance with the received signal. In the first stable state, the received signal is stable at a first signal level. In the second stable state, the received signal is stable at a second signal level. When the first stable state is detected and the received signal is changed from the first signal level into the second signal level, the generated binary signal is retained at a signal level corresponding to the second signal level, until the second stable state is detected.

1. A receiver circuit comprising:
a signal generation section that generates a binary signal based on a signal level of a received signal that has been received via a transmission line from a driver configuring a transmitter circuit, the driver having an output terminal from which a signal is transmitted to the transmission line, the signal having a first signal level when an output impedance of the output terminal is low and having a second signal level when an output impedance of the output terminal is high; a state detection section that detects a first stable state and a second stable state based on a reference signal whose signal level changes in accordance with the received signal, the first stable state being a state where the received signal is stable at the first signal level, the second stable state being a state where the received signal is stable at the second signal level; and a signal retention section that, when the first stable state is detected by the state detection section and when the received signal is changed from the first signal level into the second signal level, retains the binary signal generated by the binary signal generation section at a signal level corresponding to the second signal level, until the second stable state is detected by the state detection section.
