Abstract
A transmitting device is configured to generate a first encoded symbol and a second encoded symbol by encoding a first burst and a second burst, respectively. The transmitting device is configured to generate a first transmitting symbol and a second transmitting symbol by selectively inverting the first and second encoded symbols on the basis of a logic level of a bit with a specific sequence number of each of a previously generated transmitting symbol and the first burst.
Claims23
A transmitting device comprising:
- an inversion determination circuit configured to receive a bit with a specific sequence number of a second transmitting symbol and a bit with the specific sequence number of a first burst, configured to enable and generate a first inversion signal according to a logic level of the bit with the specific sequence number of the second transmitting symbol, and configured to enable and generate a second inversion signal according to a logic level of the bit with the specific sequence number of the first burst;
- an encoding block configured to receive the first burst and a second burst, configured to encode the first burst to generate a first encoded symbol, and configured to encode the second burst to generate a second encoded symbol;
- and
- an inversion block configured to generate a first transmitting symbol by selectively inverting the first encoded symbol based on whether the first inversion signal is enabled, and to generate the second transmitting symbol by selectively inverting the second encoded symbol based on whether the second inversion signal is enabled.

A transmitting and receiving method comprising:
- dividing output data into a first burst and a second burst;
- determining whether a bit with a specific sequence number of a second transmitting symbol has a first logic level and a bit with a specific sequence number of a first burst has the first logic level;
- generating a first encoded symbol by encoding the first burst and generating a second encoded symbol by encoding the second burst, so that a maximum transition is avoided;
- generating a first transmitting symbol and the second transmitting symbol by selectively inverting the first encoded symbol and the second encoded symbol on the basis of results of the determination;
- and
- transmitting a 4-level pulse amplitude modulation (PAM-4) signal on the basis of the first transmitting symbol and the second transmitting symbol.
