Abstract: A circuit includes phase detection circuitry, a clock signal generation circuit, a first frequency divider, and a second frequency divider. The phase detection circuitry compares an input clock signal to a feedback signal to generate a control signal. The clock signal generation circuit generates a periodic output signal in response to the control signal. The first frequency divider divides a frequency of the periodic output signal by a first value to generate a first frequency divided signal. The second frequency divider divides the frequency of the periodic output signal by a second value to generate a second frequency divided signal. The first and the second frequency divided signals are routed to the phase detection circuitry as the feedback signal during different time intervals.

Abstract: Serial data signal receiver circuitry for inclusion on a PLD includes a plurality of equalizer circuits that are connected in series and that are individually controllable so that collectively they can compensate for a wide range of possible input signal attenuation characteristics. Other circuit features may be connected in relation to the equalizer circuits to give the receiver circuitry other capabilities. For example, these other features may include various types of loop-back test circuits, controllable termination resistance, controllable common mode voltage, and a controllable threshold for detection of an input signal. Various aspects of control of the receiver circuitry may be programmable.

Abstract: The core of an IC may be supplied with a reduced voltage by an internal voltage dropping circuit VDC, while the input and output circuits remain compatible with circuits supplied with an unreduced voltage. Alternatively, the IC may be supplied with reduced voltage, and the input can be configured to accept signals from circuits supplied with the reduced voltage (figure 4), or from circuits supplied with the unreduced voltage (figure 5). When the IC is supplied with reduced voltage, an output driver (figure 9a) may be protected against leakage currents by applying a boosted voltage, e.g. from a voltage pump, to some driver nodes. The same IC design may be used in different operating modes depending on the option selected by metal masks, by fuses, or by EEPROM, EPROM, or SRAM cells.
