Abstract:
A transmitter for generating a differential signal pair including a pre-emphasis component. In an embodiment, the transmitter comprises pre-driver circuitry including an input to receive a single-ended data signal. The differential transmitter further comprises a load circuit coupled between the input and a node coupled to an output of the pre-driver circuitry which corresponds to a constituent signal of the differential signal pair. In another embodiment, the load circuit is configurable to provide a signal path between the input and the node. A configuration of the load circuit allows for a type of pre-emphasis to be included in the constituent signal.
