摘要： The invention provides a single digital communication link between system-side and line-side circuitry in a DAA, capable both of carrying data signals and of transferring a substantial amount of power to the line-side circuitry. The invention comprises a system-side interface circuit, a line-side interface circuit, and an isolation barrier including a transformer. Each interface circuit is capable of connection to an upstream communication circuit (either line-side or system-side), from which it may receive data signals to be transmitted across the isolation barrier to the other interface circuit, and to which it may pass data signals received across the isolation barrier from the other interface circuit. The line-side interface circuit may further include a rectifier and a storage device.

摘要： A system and method are provided for providing an impedance match of an output buffer to a transmission line without significantly increasing the power consumption of the output buffer. A system and method are also provided for providing an impedance match of an output buffer to a transmission line, while still allowing for an adjustable output swing as is required for loads such as laser transmitters and optical modulators.

摘要： An optical transmitter includes a laser driver capable of receiving data and applying the data to drive a laser diode over a transmission line having first and second ends. The first end of the transmission line is coupled to an output of the laser driver. A first terminal of an amplifier is coupled to the second end of the transmission line. A second terminal of the amplifier is coupled to the laser diode. The signal amplitude applied at the first terminal controls optical output amplitude of the laser diode.

摘要： A delay generator having very high accuracy and stability over temperature variations and time, suited for very short delay times, such as in clock recovery circuits in very high-speed digital data transmission systems. A delay line, having one end either open or shorted and a round-trip delay time of .tau., is driven by a voltage source, the output impedance thereof matched to the delay line, and a current source. The current source and the voltage source are driven by an input signal to be delayed. The voltage source is provided by a transistor operating as a voltage follower, which also operates to provide as an output a signal dependent on the difference between the input signal and the voltage on the delay line. This output serves as the output of the delay generator, the input signal delayed by a the time .tau..
