Abstract: An apparatus and method of generating an output transmit signal including generating a first portion of an output transmit signal based on an input transmit signal, wherein the first portion of the output transmit signal includes a first set of pulses each spanning a unit interval (UI); generating a second portion of the output transmit signal based on the input transmit signal, wherein the second portion of the output signal includes a second set of pulses each spanning a middle sub-interval of the UI; and combining the first portion with the second portion to generate the output transmit signal.

Abstract: A reconfigurable driver in an I/O circuit has a first transistor provided in a first pullup structure, a second transistor provided in a second pullup structure, and a control circuit that generates a control signal provided to a gate of the second transistor. A gate of the first transistor receives a data signal. The control signal is an inverted, delayed version of the data signal in a first mode. The control signal turns off the second transistor in a second mode. The control circuit generates the control signal using a version of the data signal when operated in a third mode. The second pullup structure may be used to provide one-shot equalization to an output of the reconfigurable driver when the second pullup structure is operated in the first mode. The second transistor may be a thin-oxide PMOS transistor. The first transistor may be a thin-oxide NMOS transistor.

Abstract: An ESD protection circuit in an interface circuit has a first diode coupled between a power source of an integrated circuit device and an input/output pad of the integrated circuit device, a second diode coupled between a first terminal of a first resistive element and the input/output pad, with a second terminal of the first resistive element being coupled to the power source, a second resistive element that couples the second diode to the first diode and to the input/output pad; a first clamping circuit coupled between the power source and a ground reference of the integrated circuit device, and a second clamping circuit coupled between the first terminal of the first resistive element and the ground reference. The power source supplies a driver circuit coupled to the input/output pad.
