Abstract: A clock data recovery system is described. It includes a high pass filter for transmitting a filtered data signal in response to receiving an input data signal; an adder for summing the filtered data signal with a feedback signal, wherein the adder produces a summed input signal; a plurality of clocked data comparators for receiving the summed input signal, wherein the clocked data comparators determine an input data bit value; a plurality of clocked error comparators for receiving an error signal associated with clock recovery; an equalization and adaptation logic for selecting an error sample such that a phase associated with the error sample is locked at a second post cursor; and a phase mixer for transmitting a delay in response to receiving the phase and the delay is transmitted to the clocked-data comparators and the clocked-error comparators.

Abstract: In an integrated circuit receiving multiple serial data streams in parallel, a local clock is generated from each data stream and is synchronized with the data stream. Sometimes a data stream may have no transitions making it difficult to keep the clock synchronized with its data. A clock channel is provided, which always has edges. A circuit is provided for each data stream which measures the time elapsed since the data stream had an edge. After a certain period, the phase of the local clock is nudged towards that of the clock channel. Thereafter, the longer there are no edges on the data stream the more frequently nudges towards the phase of the clock channel are made.

Abstract: A circuit for receiving multiple serial datastreams in parallel is disclosed. A bit clock is recovered from each data stream, there being one data bit for each transition of the clock signal both positive and negative going. The phases of the bit clocks are compared and are adjusted by 180 degrees so that the positive going edges of all occur close to each other. The bits of each stream are assembled into words under the control of a word clock. In one embodiment a common word clock is derived form the set of bit clocks as a whole. In another embodiment each stream is provided with its own word clock which is aligned to positive edges of the respective bit clocks that are close to each other.
