Abstract: Methods and systems are provided for multi-chip receivers with loop-through feeds. A receiver that comprises plurality of chips may receive one or more input feeds, with each of the chips generating a corresponding output comprising data (e.g., channels) extracted from the one or more input feeds. Only a first chip may handle reception and/or initial processing of the one or more input feeds, with each one of the remaining chips processing a loop-through feed generated in the first chip, in order to generate the corresponding output of that chip. The loop-through feed may be generated based on the one or more input feeds. In this regard, the loop-through feed may comprise at least one of the one or more input feeds that is partially processed in the first one of the plurality of chips.

Abstract: A coupling device for use in a hybrid fiber coaxial (HFC) network may be configured to disable an upstream path through it when there is only noise incident on the upstream path, and enable the upstream path through it when a desired transmission from a cable modem downstream of the coupling device is incident on the upstream path. The coupling device may be a trunk amplifier, a distribution amplifier, a splitter, or the like. The coupling device may comprise a single upstream interface coupled to a plurality of downstream interfaces. The enabling and/or disabling may be in response to a signal strength indicated by the SSI being below a threshold and/or in response to one or more control messages indicating whether any downstream cable modem is, or will be, transmitting.

Abstract: A network device may receive a signal from a headend, wherein a bandwidth of the received signal spans from a low frequency to a high frequency and encompasses a plurality of sub-bands. The network device may determine, based on communication with the headend, whether one of more of the sub-bands residing above a threshold frequency are available for carrying downstream data from the headend to the circuitry. The network device may digitize the signal using an ADC operating at a sampling frequency. The sampling frequency may be configured based on a result of the determining. When the sub-band(s) are available for carrying downstream data from the headend to the network device, the sampling frequency may be set to a relatively high frequency. When the sub-band(s) are not available for carrying downstream data from the headend to the network device, the sampling frequency may be set to a relatively low frequency.
