1. A serial communication link, comprising:
- a receiver; and
a transmitter coupled to the receiver by a first serial communication lane operating at a first speed in a first mode and in a second mode, and by a second serial communication lane operating at the first speed in the first mode and at a second speed in the second mode, the second speed being slower than the first speed.

Abstract
A serial communication link includes a receiver and a transmitter coupled to the receiver by a first serial communication lane operating at a first speed, and a second serial communication lane operating at a second speed. The second speed is slower than the first speed. The transmitter can include bit steering logic that receives a data stream, provides a first number of bits of the data stream to the first serial communication lane, and provides a second number of bits to the second serial communication lane. The proportion of the first number of bits to the second number of bits is the same as a proportion of the first speed to the second speed.
