MULTIPLE PORTS WITH DIFFERENT BAUD RATE OVER A SINGLE SERDES

Various examples of the present disclosure relate to a transmitter apparatus, device, method, and computer program, to a receiver apparatus, device, method, and computer program, and to corresponding source and destination devices and communication devices. The transmitter apparatus comprises a plurality of ports for data to be transmitted to a destination device, with each port being associated with a transmission data rate. The transmitter apparatus comprises processing circuitry configured to obtain data to be transmitted to the destination device via the plurality of ports. The processing circuitry is configured to multiplex the data to be transmitted to the destination device according to a weighted round-robin scheme to generate a multiplexed data stream. The weights of the weighted round-robin scheme are based on the transmission data rate of the respective port the data is obtained over. The processing circuitry is configured to transmit the multiplexed data stream to the destination device.
