Networking devices use high-speed differential signaling that can exceed 10 Gbps. Circuit design for the transmitter (TX) and receiver (RX) elements in the high speed channel have capabilities of offset signal losses in the PCB and system. This session will review the high-speed signal channel and its characteristics and illustrate how the TX and RX circuits in general are used to offset signal losses. It will also show key characteristics of the channels that are needed to allow these TX and RX circuits to work effectively. This session will also address maximum length of the PCB channel, PCB-specific structures that need to be optimized and the usage of the IBIS-AMI models for 5-10 Gbps operation. Examples of channels from PCB designs at NXP will also be included.
