Abstract
A circuit, set forth by way of example and not limitation, includes a signal detector operative to detect two types of signals, where the two types of signals include a higher-frequency signal and a lower-frequency signal. The signal detector is operative to detect that a received input signal is one of the two types of signals. An output driver is operative to receive the input signal and to adjust conditioning performed on the input signal to create an output signal for transmission over a communication channel, where the adjustment is based on the detection by the signal detector.
Claims18
A circuit comprising:
- a signal detector operative to detect two types of signals, wherein the two types of signals include a higher-frequency signal and a lower-frequency signal, and wherein the signal detector is operative to detect that a received input signal is one of the two types of signals;
- and
- an output driver operative to receive the input signal and to adjust conditioning performed on the input signal to create an output signal for transmission over a communication channel, wherein the adjustment is based on the detection by the signal detector;
- wherein the signal detector includes a retriggerable monostable block that is triggered by the received input signal.
A signal detector comprising:
- an electrical idle detector coupled to an input and operative to detect an input signal on the input;
- and
- a circuit coupled to the input and to the electrical idle detector, the circuit operative to detect two types of signals, wherein the two types of signals include a control signal and a data signal, and wherein the circuit is operative to detect that the input signal on the input is one of the two types of signals,
- wherein the circuit provides a detector signal used to indicate the type of signal of the input signal to an output driver for use in adjusting conditioning performed on the input signal for output over a communication channel.
A method comprising:
- receiving an input signal at a signal detector operative to detect two types of signals, wherein the two types of signals includes a higher-frequency signal and a lower-frequency signal;
- determining that the input signal is one of the two types of signals;
- and
- adjusting conditioning performed on the input signal based on the detected type of signal to create an output signal for transmission on a communication channel;
- wherein the higher-frequency signal is a data signal and the lower-frequency signal is a control signal.
