Abstract: A frequency multiplier circuit includes a first multiplier circuit to generate a first digital value representing a received reference signal having a reference frequency and reference phase, the multiplier circuit to multiply the first digital value by a multiplier value. Comparison circuitry compares the first digital value to an output digital value representing an output signal having an output frequency and an output phase, the comparison circuitry to generate an error signal based on the comparison. A programmable loop filter generates a control signal based at least in part on the error signal. A frequency generation circuit produces the output signal having the output frequency and phase. A phase-to-digital converter generates and feeds the output digital value to the phase comparison circuitry. A programmable transition controller controls a transitioning frequency relationship between a first signal frequency of a first locked output signal and a desired second signal frequency.

Abstract: A high-speed universal serial bus (USB) transceiver includes a voltage-mode architecture for generating a USB signal. The voltage mode architecture reduces power consumption by reducing the current requirements for high-speed USB communications. The USB transceiver can include a reference voltage generator, a resistive element, and a switching element for completing and breaking a circuit including the reference voltage generator, the resistive element, and a data pin of a USB port to generate half of the differential USB signal (e.g., the D+ signal). A similar circuit can be used to generate the other half of the differential USB signal (i.e., the D? signal). The resistive element can be a set of parallel resistors in the transceiver, with the set of parallel resistors being specifically selected from a larger population of resistors to provide the specified resistance (45?±10%) in the USB transceiver.

Abstract: A mixed signal integrated circuit includes a signal source to inject a test signal into the signal path of the mixed signal integrated circuit, a feedback loop and a signal comparator for determining characteristics of a resulting signal. Conveniently, the test signal may be a digital signal injected upstream of a digital to analog converter (DAC). By connecting the output to the input, the entirety of the signal path and the majority of the integrated circuit may be tested. The signal may be condition or manipulated in the feedback loop. By incorporating test signal generation and measurement into the mixed signal integrated circuit, the cost of test equipment and the test duration for each device under test may be reduced.

Abstract: This invention relates to a low loss liquid processing system used for manufacturing personal care and cleaning compositions, in particular oral care compositions such as dentifrice, mouthrinse and denture care products. The present process addresses manufacturing flexibility issues involved in making products to demand and the ability to proactively monitor intermediate compositions for quality assurance purposes. Specifically, the present manufacturing process provides faster variant turnaround times, shorter clean-up times between variants, significant material waste reduction and smaller effluent volumes than those of typical batch systems. As well, a process has been developed for more efficient addition of materials which are dissimilar in chemical composition and/or physical parameters to the original base material or of materials which may be temperature and shear sensitive.

Abstract: A Universal Serial Bus (USB) 2.0 transceiver includes a legacy full speed and low speed (FS/LS) USB driver that includes multiple output stages. The multiple output stages are connected in parallel to an output terminal. By sequentially providing the USB data to the multiple output stages, the USB signal at the output terminal will transition between logic states in an incremental fashion as the multiple output stages sequentially switch their individual output states. Consequently, the rise/fall time for the legacy FS/LS USB driver is controlled not by the strength of the inverter transistors in the output stages, but rather by the number of stages and the time interval between application of the USB data to each stage. Therefore, by selecting an appropriate number of output stages and an appropriate timing interval, accurate control over full speed and low speed USB signal rise/fall times can be provided.
