  • Patent number: 6980588
    Abstract: An apparatus for handling high speed data communication signals in at least one input channel. Each communication signal is encoded in signal excursions in at least one predetermined format. The apparatus includes: (a) at least one input locus coupled with each input channel for receiving the signals; (b) at least one output locus for presenting selected communication signals in a desired format in at least one output channel; and (c) a plurality of treating circuits for treating the signal excursions in a plurality of formats that include the predetermined format and the desired format. Each treating circuit is coupled with at least one respective input locus and at least one respective output locus. The apparatus presents sufficiently low capacitance between input loci and output loci to impart substantially zero time delay to the communication signals.

  • Patent number: 6847232
    Abstract: A system and method is described for a driver circuit used for high speed data transmission in LVDS and CML transceiver device applications. The transceivers are intended to receive a low voltage differential input signal and interchangeably drive a standard LVDS load with a TIA/EIA-644 compliant LVDS signal, and a standard CML load with a standard CML compatible signal. The driver circuit operates at speeds up to 1.36 Gbps, making it compatible with the OC-24 signaling rate for optical transmission. To accomplish this, the driver uses a mixed combination of voltage and current mode drive sections in the output circuit when coupled to LVDS loads, and when the driver is coupled to CML loads, operates purely in a current mode using only the current mode drive section.

  • Patent number: 5914643
    Abstract: A CMOS oscillator includes two differential input transistors (150) and (152) which have the sources thereof coupled through a resonator element (196). Active loads (166) and (178) provide a squaring up of the output which then drives an output transistor (202). The gates of the differential input transistors (150) and (152) are biased to predetermined voltage levels with bias circuits, with the positive input of the comparator configuration coupled through a feedback capacitor (208) to the output (204). This provides sufficient instability to initiate oscillation with a gain of the device controlled by resonator circuit (196) to be optoimum at the resonant frequency of the resonator circuit.
