摘要： A system, method, and apparatus for providing an embedded controller in a modem device for enabling data communication between different networks. Management and control capabilities for a gateway function are embedded into a communication controller of the modem device so as to enable direct connection between wired and wireless devices while eliminating a separate gateway controller. A single controller in the modem device, wired or wireless, manages its own designated communication functions and data exchange between the two different networks.

摘要： In various embodiments, applicants' teachings are related to an active guarding circuit and method for reducing parasitic impedance signal loading on a signal-transmission channel that is shunted by a parasitic impedance. The presence of an electrical signal on the signal-transmission channel causes a leakage current to flow through the parasitic impedance. In various embodiments, the circuit comprises an amplifier and an impedance, one terminal of the impedance is coupled to the signal-transmission channel. The input of the amplifier is coupled to the signal-transmission channel and the output is coupled to the other terminal of the impedance so as to cause a compensation current to flow through the impedance. The gain of the amplifier and the value of the impedance are selected so that the compensation current has a magnitude substantially equal to the leakage current magnitude.

摘要： A phase detector includes a counter to generate the integer portion of a number of complete cycles of an output clock at each active edge of a reference clock. A time to digital converter in the phase detector generates the fractional portion of the number of complete cycles of the output clock at each active edge of the reference clock. The sum of the fractional portion and the integer portion is subtracted from an accumulated value obtained by accumulating a pre-determined number to generate an error signal as the output of the phase detector. The counter is read at an active edge of one of two re-timed clocks derived from the reference clock. Each of the two re-timed clocks is generated based on a comparison of the fractional portion with a pair of thresholds. Errors due to metastability in reading the counter are thereby avoided.
