An improved dither generation circuit and method for digital audio circuits generates pseudo-random numbers that are then interpreted as 2s complement numbers representing data points of a bipolar signal. The random number signal is high-pass filtered to reduce the energy contained in the audio band. The resulting dither signal is applied to the circuit in its main feedback loop and is effective to prevent idle tones. Because of its spectrally shaped characteristic this dither signal introduces less noise into the audio band of interest and thereby improves the overall signal-to-noise ratio of the audio circuit.

Provided is a system and method for converting digital data audio data audio data that has a predetermined input sample rate, into an analog data signal. A system includes a digital to analog converter (DAC) including a digital processing portion configured to receive as an input the digital audio data and timing information, the timing information being representative of a time base of the input sample rate. The digital processing portion is similarly configured to digitally process the digital audio data and the timing information to produce serialized output data. The DAC also includes an analog processing portion configured to convert serialized data to an analog format. The digital processing portion operates in accordance with at least one clock having a corresponding clock rate wherein the corresponding clock rate is unrelated to the input sample rate.

A communication system for coupling telephony or other signals to a broadband network such as a CATV network. The system transmits a multiplex of telephony signals in the forward band of the broadband network, with individual signals directed to an addressed subscriber. Telephony signals returning from subscribers upstream to a headend unit (HIU) are modulated onto the reverse band of the broadband network in a frequency division multiple access (FDMA) arrangement. The upstream modulated telephony signals are received at a telephony network interface at the HIU coupled to the broadband network. A group of reverse band modulated telephony signals are received at a group receiver or channelizer. The group receiver processes all upstream telephony signals within a selected spectral subband in the reverse band to apply a receiver matched filter with a weighted overlap and add circuit, and are then converted to baseband by an FFT circuit. The group receiver provides a serial data stream representing the baseband telephony signals.

A communications management system introduces a low bandwidth phase locked loop (LoBW-PLL) working in tandem with a high bandwidth phase locked loop (HiBW-PLL). The LoBW-PLL only needs to follow the average frequency of the transported clock and not all of the excursions made by the master clock. During periods of downstream outage, the LoBW-PLL opens its loop and free wheels such that disturbances caused by a reacquisition do not impact the concept of time for the LoBW-PLL. After reacquisition, the LoBW-PLL and HiBW-PLL are compared to determine if a timing error has occurred. If a timing error is detected, the magnitude of the timing error is measured upon completion of the reacquisition cycle, and this measurement is used to correct the timing error.

A system and method are used to provide uncorrelated code hopping in a communications system. A multi-bit linear shift register receives data and clocks the data fifteen times. A word assembler receives the shifted data and outputs a fifteen bit word. A mixer mixes the fifteen bit word with an numerical value of active codes to generate a mixed signal. A divider divides the mixed signal to produce a divided signal. A truncator truncates the divided signal to its seven most significant bits to produce a pseudo random hop number. A code matrix shifter circularly shifts the active codes in a code matrix based on the pseudo random hop number to produce a circularly shifted code. A transmitter transmits the circularly shifted code matrix.

A signal recovery system and methods to quickly acquire signal lock and maintain consistent performance of the signal recovery system for different signal input rates of an input signal are provided. The system includes a phase locked loop system and a parameter controller. The method includes monitoring an input signal, determining a signal input rate of the input signal, providing shift factors to a loop filter contained within the signal recovery system, and adjusting the phase locked loop system performance based on the shift factors. The performance factors that can be modified include the acquisition rate, loop bandwidth, and damping factor of the phase locked loop system within the signal recovery system.

All digital reference frequency locking. An all digital approach is provided for operation within one or more CMs within a cable modem communication system to lock the upstream of the one or more CMs to the downstream symbol clock provided from a CMTS. The locking of the CM's upstream may be performed using one of at least three different functions: (1) Locking the upstream symbol clock phase to the downstream symbol clock phase, (2) Locking the downstream symbol clock phase to the headend reference clock phase (typically 10. 24 MHz or integer multiple thereof), and (3) Locking the upstream carrier frequency to the downstream symbol clock frequency. The all-digital techniques for supporting all digital reference frequency locking functionality provide high performance to support S-CDMA and other synchronous modulation techniques.
