Abstract
Signal processing circuitry having parallel processing channels has clock-generation circuitry that generates (i) high-speed clock signals used to drive the channels and (ii) synchronization signals used to reset the processing of the channels. In one embodiment, the signal processing circuitry has multiple multiplexing channels arranged in one or more macrocells, each macrocell having one or more channels and a phase-locked loop (PLL) that generates a high-speed PLL clock signal and a synchronization signal for the macrocell's channels. Each channel has a counter that implements a state machine used to drive the multiplexing processing, where the state machine is reset to a specified state upon receipt of each synchronization pulse in the synchronization signal.
