Active single-ended transmission cable
An active single-ended transmission cable is disclosed. The active single-ended transmission cable allows connection between a first and a second electronic device and comprises a first port, a second port, and a transmission wire. The first or second port is used for receiving or transmitting a differential signal between the first and the second electronic devices, and for converting between a differential signal and a single-ended signal. The transmission wire is used for transmitting the single-ended signal. This allows the conversion between the received or transmitted differential signal at the first and second ports into the single-ended signal so as to allow the transmission of the single-ended signal within the transmission wire.
1 . An active single-ended transmission line, which is connected between a first electronic device and a second electronic device, the active single-ended transmission line comprising:
a first connector port;
a second connector port, wherein either the first connector port or the second connector port can be respectively connected to the first electronic device or the second electronic device for receiving or transmitting a differential signal between the first electronic device and the second electronic device and converting the differential signal into a single-ended signal; and
a transmission wire connecting between the first connector port and the second connector port to transmit a single-ended signal; thus, the differential signal received or transmitted by the first connector port and the second connector port can be converted into the single-ended signal so as to transmit the single-ended signal within the transmission wire; wherein the first connector port includes a first gain module, and the second connector port includes a second gain module, wherein the first gain module and the second gain module are used to compensate for a loss of gain during the conversion of the differential signal to the single-ended signal for transmission and compensate for the loss on the transmission path.
2 . The active single-ended transmission line as claimed in claim 1 , wherein the first gain module includes a first flat gain module, a first peak gain module, and an output buffer module; the first flat gain module compensates for broadband gain loss; the first peak gain module compensates for frequency-dependent channel loss; and the output buffer module converts the differential signal into the single-ended signal.
3 . The active single-ended transmission line as claimed in claim 1 , wherein the second gain module includes an input buffer module, a second flat gain module, and a second peak gain module; the input buffer module converts the single-ended signal into the differential signal; the second flat gain module compensates for broadband gain loss; and the second peak gain module compensates for frequency-dependent channel loss.
