Abstract
In one embodiment, an integrated circuit has one or more multi-channel transmitters, each transmitter having synchronization circuitry that synchronizes different copies of a reset signal used to reset different sets of TX channel circuitry used to generate the multiple TX signals, to reduce the skew between the different TX signals. Each set of synchronization circuitry has (at least) two synchronization stages that re-time different copies of the reset signal to a selected clock signal. In one implementation, the integrated circuit has (at least) two quads, each of which can generate four different TX signals, where both quads can be configured to use the same clock signal to re-time different copies of the reset signal such that the eight different TX signals are all synchronized to one another.
