ABSTRACT:
A method for receiving data by an integrated circuitry chip includes receiving data signals and a first clock signal sent by a sending chip. The data signals are received by data receivers and the clock signal is received by at least one clock receiver of the receiving chip. A reference voltage is derived by reference voltage circuitry for the receiving chip responsive to the first clock signal. Logical states of the received data signals are detected. The detecting includes the data receivers comparing voltage levels of the received data signals to the derived reference voltage.
