Abstract: A serializer and deserializer utilize upsampling and downsampling to operate over a broad range of frequencies. The serializer includes a bit repeater and a high-speed serializer. The bit repeater receives data to be serialized, upsamples the received data, and supplies the upsampled data to the high-speed serializer. The deserializer includes a high-speed deserializer and a downsampler. The high-speed deserializer supplies parallelized data to the downsampler. The downsampler decimates the parallelized data and supplies the decimated data to an output of the deserializer.

Abstract: A clock and data recovery device receives a serial data stream and produces recovered clock and data signals. The clock and data recovery device operates over a range of frequencies and without use an external reference clock. A first loop supplies a first clock signal to a second loop. The second loop modifies the first clock signal to produce the recovered clock signal and uses the recover clock signal to produce the recovered data signal. The first loop changes the frequency of the first clock signal based on frequency comparison and data transition density metrics.

Abstract: A clock and data recovery device recovers data from a sequential stream of data that includes bursts of data separated by gaps. Each burst of data arrives with its own phase and with its own deviation from a nominal frequency. The bursts of data begin with a preamble that is utilized to determine the timing of the burst. The clock and data recovery device determines the timing of a burst of data using signals from one or more demultiplexers or samplers. At the start of each burst of data, sampled input signals are analyzed by an edge detector to determine a sample phase for the burst. A selector utilizes the sample phase determined by the edge detector to choose which of the sampled input signals to use to produce output data signals from the clock and data recovery device.
