Abstract: The present invention is an integrated cable modem tuner. In one embodiment, the upstream path and the downstream path are integrated on a common semiconductor substrate. The down-stream path can include a TV tuner and digital receiver portion that is integrated on a common semiconductor substrate with the power amplifier of the upstream path. In another embodiment, the TV tuner is implemented on a first semiconductor substrate and the digital receiver portion and the power amplifier are configured on a second semiconductor substrate. However, the two substrates are mounted on a common carrier so that the cable modem appears to be a single chip configuration to the user.

Abstract: Distortion and aliasing reduction for digital to analog conversion. Synthesis of one or more distortion terms made based on a digital signal (e.g., one or more digital codewords) is performed in accordance with digital to analog conversion. The one or more distortion terms may correspond to aliased higher-order harmonics, distortion, nonlinearities, clipping, etc. Such distortion terms may be known a priori, such as based upon particular characteristics of a given device, operational history, etc. Alternatively, such distortion terms may be determined based upon operation of a device and/or based upon an analog signal generated from the analog to conversion process. For example, frequency selective measurements made based on an analog signal generated from the digital to analog conversion may be used for determination of and/or adaptation of the one or more distortion terms. One or more DACs may be employed within various architectures operative to perform digital to analog conversion.

Abstract: A communication device is implemented to perform signal processing based on different dynamic ranges at different times. The device can operate with a first, relatively larger dynamic range during normal operations, and with a second, relatively smaller dynamic range during reduced power or sleep mode operations. The relatively smaller dynamic range may have a relatively higher noise floor than the larger dynamic range. Generally, any desired number of different dynamic ranges may be used at different times and based on different operating conditions. The communication device can include functionality associated with two or more transceivers to support communications based on two or more power modes (e.g., a full power mode, a reduced power mode or a sleep mode, etc.). The communication device may alternatively include two or more separate transceivers to support such communications. An unused transceiver or transceiver functionality may be turned off to provide power savings.
