摘要： A novel passive circuit for providing improved common mode rejection of a differential amplifier novel. The passive circuit functions to compensate for amplitude mismatches between the two outputs of a differential amplifier. To compensate for the amplitude mismatch between the output traces of the amplifier, a resistor is inserted in series with at either one or both of the differential outputs. The values of the resistors are set such that the mismatch is substantially eliminated. Inductors are connected in parallel with the resistors to create a zero ohm path for power. At high frequencies the inductor impedance is sufficiently high that the series resistor compensates for the imbalance caused by spurious products. The imbalance in the amplifier outputs is corrected with the resulting increase in the rejection of spurious frequency products by exploiting the differential common mode rejection (CMR) effect of the differential amplifier.

摘要： In a novel apparatus for and method of discrete spurious frequency leakage cancellation a radio frequency RF switch is used to couple the upstream path signal to the CATV cable only during transmission bursts. In between transmission bursts, the upstream signal is disconnected from the CATV cable. In a circuit for canceling frequency spurs from a victim signal, a radio frequency (RF) switch is operative to connect and disconnect the victim signal to/from the output in accordance with a switch control signal which is generated by a switch control module. The victim signal is coupled to said RF switch output during transmission bursts only.

摘要： A novel apparatus for and method of discrete spurious frequency leakage cancellation for use in a cable modem. The spurious leakage cancellation mechanism is particularly suitable for use in cable modem systems adapted to implement the DOCSIS 2.0 specification which specifies both downstream and upstream channels. In one embodiment, the spurious emission cancellation mechanism cancels the spurious emissions by first creating a replica of the aggressor clock signal having the same amplitude but 180 degree phase shift as the spurious signal. The phase shifted spurious replica is added to the original spurious signal thus cancelling the spurious signal. In another embodiment, an RF switch is used to couple the upstream path signal to the CATV cable only during transmission bursts. In between transmission bursts, the upstream signal is disconnected from the CATV cable. This embodiment takes advantage of the less stringent spurious requirements in the DOCSIS 2.0 specification for transmission bursts. In between transmission bursts, when stricter spurious requirements apply, the upstream signal is disconnected from the CATV cable.

摘要： A novel apparatus and method of reduced power consumption for battery backup operation of a communication device such as a cable modem. When the cable modem senses a failure of the external power source it requests from the cable head-end to switch from multi-channel DOCSIS 3.0 operation to single-channel DOCSIS 2.0 operation. In response to approval by the cable head-end, the cable modem shuts down multi-channel circuits in the PHY such as the wideband analog to digital converter (ADC) which is normally used during multi-channel operation. In its place, it activates narrowband circuitry such as a narrowband ADC which consumes far less power. Tuner filter circuits are also swapped to match the reduced bandwidth requirements of battery backup operation. To further reduce power, the narrower bandwidth requirements during battery backup operation permit the linearity of a programmable gain amplifier (PGA) in the upstream path to be reduced.

摘要： A novel single chip tuner integrated circuit (IC) for multiple video reception in a cable modem. The tuner circuit is well suited for use in cable modem systems adapted to implement the DOCSIS 3.0 specification which specifies multiple simultaneous video channel reception. The single-chip tuner integrated circuit comprises a plurality of tuner sub-circuits wherein each tuner sub-circuit is operative to generate a single output channel, determined in accordance with a tune commend input. The tune command input is used to generate a frequency reference signal that is input to a corresponding tuner sub-circuit. The frequency reference signal for a tuner sub-circuit is mixed with an input RF receive signal from the CATV input to the cable modem to generate a baseband channel.
