Abstract
A system including a driver circuit. The driver circuit is configured to provide first output signals in a first mode for electrical signaling and second output signals in a second mode for optical signaling. The driver circuit is configured to provide the first output signals in the first mode with at least one of a lower frequency and higher power and the second output signals in the second mode with at least one of a higher frequency and lower power.
Claims17
A system, comprising:
- a first driver circuit and a second driver circuit, each of the first and second driver circuits configured to selectively provide first electrical output signals in a first mode with lower frequency and higher power for electrical signaling, and second electrical output signals in a second mode with higher frequency and lower power for optical signaling;
- an electrical-to-optical converter configured to receive the second electrical output signals from the first driver circuit selectively set to the second mode, and to convert the second electrical output signals from the first driver circuit to optical signals;
- an electrical component configured to receive the first electrical output signals from the second driver circuit selectively set to the first mode;
- and
- an integrated circuit to:
- in response to determining that the first driver circuit is in the second mode, provide data without error correction to the first driver circuit in the second mode, and
- in response to determining that the second driver circuit is in the first mode, provide data with the error correction to the second driver circuit in the first mode.

A method comprising:
- selectively setting a first driver circuit into one of a first mode and a second mode, and selectively setting a second driver circuit into one of the first mode and the second mode, wherein in the first mode each of the first and second driver circuits outputs first electrical output signals with a lower frequency and higher power for electrical signaling, and wherein in the second mode each of the first and second driver circuits outputs second electrical output signals with a higher frequency and lower power for optical signaling;
- routing the second electrical output signals from the first driver circuit selectively set to the second mode to an electrical-to-optical converter;
- routing the first electrical output signals from the second driver circuit selectively set to the first mode to an electrical component;
- and
- in response to determining that the first driver circuit is in the second mode, providing, by an integrated circuit, data without error correction to the first driver circuit in the second mode;
- and
- in response to determining that the second driver circuit is in the first mode, providing, by the integrated circuit, data with the error correction to the second driver circuit in the first mode.
