Abstract
Methods and apparatuses for adaptable receiver detection are provided. Embodiments include providing, by receiver detection circuitry at a transmitter coupled to a communication link, a voltage to the communication link; determining, by the receiver detection circuitry, a rise time corresponding to a rising edge change of the voltage on the communication link; determining, by the receiver detection circuitry, a fall time corresponding to a falling edge change of the voltage on the communication link; and determining, by the receiver detection circuitry, whether the rise time and the fall time are consistent with the transmitter being coupled through the communication link to a remote receiver.
