Abstract
An integrated circuit (IC) device, system and related method of communicating data are described. The IC device includes; a data port configured to provide output data to a channel and receive input data from the channel, an impedance matching circuit connected to the data port and configured to operate as an output driver circuit when the output data is being transmitted and as an on die termination circuit when the input data is being received, and an active inductive bias circuit connected to the data port in parallel with the impedance matching circuit, and configured to adjust the impedance of the data port to the channel during transmission of the output data as a function of output data frequency and adjust the impedance of the data port to the channel during receipt of the input data as a function of input data frequency.
