Abstract

Techniques for sampling a data signal are described. An example of an electronic device includes a data bus, a transmitting device coupled to the data bus, and a receiving device coupled to the data bus by a bus interface. The bus interface is to receive a data signal from the transmitting device, wherein the data signal includes a known data pattern. Additionally, the bus interface is to receive a forwarded clock signal from the transmitting device and generate a sampling clock signal based on the forwarded clock signal. Additionally, the bus interface is to sample the known data pattern to obtain phase tracking data and adjust a sampling phase of the sampling clock signal based on the phase tracking data.
