Transmit-side active signal management circuitry applies one or more active signal management processes to a digital signal at a transmit side of an interconnect. At the receive side of the interconnect, receive-side active signal management circuitry applies one or more corresponding active signal management processes, as appropriate, to the received digital signal to recover the information represented by the original digital signal. The interconnect can include a cable used to transmit the signals between a source device and a destination device, whereby one or both of the transmit-side active signal management circuitry and the receive-side active signal management circuitry is implemented at a corresponding cable receptacle of the cable. Alternately, one or both of the transmit-side active signal management circuitry and the receive-side active signal management circuitry can be implemented at a cable adaptor, thereby permitting the use of a passive cable interconnect to transmit the signal.

An output buffer utilizes capacitive feedback to control the output slew rate largely independent of load capacitance. The invention slows the rising and falling slew rates and via a capacitance feedback reduces the effect of load capacitance on slew rate, and uses no DC current. Transistor switches are employed to isolate and reduce noise and interaction among the circuit components and functions.

A technique for operating a delay circuit is disclosed. In one particular exemplary embodiment, the technique may be realized by a delay circuit comprising a plurality of data paths. The delay circuit may receive a signal. The delay circuit may also stagger transmissions of the signal through the plurality of data paths. The delay circuit may additionally generate a plurality of signals based on the staggered transmissions. Each of the plurality of data paths in the delay circuit may comprise at least one of an inverter, a logic gate, a flip-flop, a latch, a register, or a resistor-capacitor (RC) delay element.

Clock signal timing cells, clock signal timing circuits, clock circuits, memory devices, systems, and method for altering the timing of a clock signal are disclosed. An example method for altering the timing of an output signal provided responsive to an input clock signal includes adjusting a transition of an edge of the output signal from one voltage level to another based at least in part on a bias signal. An example clock signal timing cell includes an inverter and a bias controlled inverter coupled in parallel to the inverter. The bias controlled circuit is configured to provide an output signal wherein a transition of a clock edge of the output signal between first and second voltage levels is based at least in part on a bias signal.
