    摘要: A method for performing analysis of electrical signals in a system is disclosed. The system includes at least two circuit elements between which an electrical signal is transmitted. The method converts the electrical signal to dual optical signals, one of which is converted back to an electrical signal for receipt by the intended circuit element. The second optical signal may be transmitted a great distance, relative to electrical signals, allowing for remote analysis of the signal. The loss in converting the electrical signal to an optical signal, then back to an electrical signal is low compared to other debug methods. The method may be performed with high-speed signals.

    摘要: CMOS optical receiver and optical transmitters are described. The optical receiver is formed from a CMOS CCD which is modified to immediately output all information indicative of incoming light, i.e., with no transfer gate. The optical transmitter is formed of a modulation window device. Both the optical transmitter and optical receiver are located on-chip with a microprocessor and form the I/O for the microprocessor. Since the modified I/O is serial, a serial to parallel converter, and parallel to serial converter are provided.

    摘要: According to some embodiments, time domain reflectometry based transmitter equalization is provided. For example, a reflection detector in a transmitter may detect a reflection signal associated with a calibration signal that was transmitted via an interconnect. The reflection detector may then provide filter information to a transmitting unit to facilitate a transmission of data to a remote receiver via the interconnect. According to some embodiments, the receiver adjusts a termination impedance before the calibration signal is transmitted.
