1. Interface circuitry for an active cable, the interface circuitry comprising:
a first active cable interface configured for coupling to a first end of the active cable, and a second active cable interface configured for coupling to a second end of the active cable, the first active cable interface including:
first transmitter circuitry including one of (a) linear driving circuitry for a signal, and (b) non-linear driving circuitry for a signal, and
first receiver circuitry including one of (c) linear receiving circuitry for a signal, and (d) non-linear receiving circuitry for a signal; and
the second active cable interface including:
second transmitter circuitry including (a) the linear driving circuitry for a signal when the first receiver circuitry includes the non-linear receiving circuitry, and (b) the non-linear driving circuitry for a signal when the first receiver circuitry includes the linear receiving circuitry, and
second receiver circuitry including (c) the linear receiving circuitry for a signal when the first transmitter circuitry includes the non-linear driving circuitry, and (d) the non-linear receiving circuitry for a signal when the first transmitter circuitry includes the linear driving circuitry.
