Configurable differential to single ended IO |
摘要 |
An electronic system having a power efficient differential signal between a first and second electronic unit. A controller uses information, such as compliance with data transmission rate requirement and bit error rate (BER) versus a BER threshold to control power modes such that a minimal amount of power is required. Amplitude of transmission and single ended or differential transmission of data are examples of the power modes. The controller also factors in a failing phase in a differential signal in selecting a minimal power mode that satisfies the transmission rate requirement of the BER threshold. |

1. An electronic system comprising:
a first electronic unit and a second electronic unit, the first electronic unit and the second electronic unit coupled by a resistively terminated_differential signal, the resistively terminated differential signal further comprising a true phase and a complement phase; and a controller configured to reduce power dissipated during transmission of data from the first electronic unit to the second electronic unit on the differential signal by configuring a driver and a receiver of the resistively terminated_differential signal to select between a lower power mode and a higher power mode based on information about the transmission of data. |
