Embodiment Construction

[0007]Various embodiments of a serial-to-parallel converter are disclosed. In one embodiment, the serial-to-parallel converter includes a sampling unit that may, in response to a serial clock signal, sample an input serial data stream having even and odd data bits, provide an even serial data stream including the even data bits, and provide an odd serial data stream including the odd data bits. The serial-to-parallel converter also includes a strobe generator and a number of latches. The strobe generator may be configured to receive the serial clock signal and to generate a plurality of enable signals based upon the serial clock signal. The frequency of a given enable signal corresponds to a fractional multiple of a frequency of the serial clock signal. For example, the enable strobes may operate at one-fourth the frequency of the serial clock signal. The latches may latch the even data bits and the odd data bits, and in response to a particular respective enable signal, each of a f...

Abstract

A serial-to-parallel converter includes a sampling unit that may, in response to a serial clock signal, sample a serial data stream and provide an even serial data stream, and an odd serial data stream. The serial-to-parallel converter also includes a strobe generator and a number of latches. The strobe generator generates a plurality of enable signals based upon the serial clock signal. The frequency of a given enable signal corresponds to a fractional multiple of a frequency of the serial clock signal. In response to a particular respective enable signal, each of a first portion of the latches may latch and output a particular respective even data bit. Each of a second portion of the latches may latch and output a particular respective odd data bit. The serial-to-parallel converter further includes a number of output flip-flops to output the data bits in parallel in response to an output clock signal.

Description

BACKGROUND[0001]1. Technical Field[0002]This disclosure relates to data conversion, and more particularly to serial to parallel conversion.[0003]2. Description of the Related Art[0004]Systems that employ communication links with serializer-deserializer (SerDes)-based interconnects typically require receiver circuitry to serialize and deserialize the data between serial and parallel data formats. Many systems are now employing serial links to transfer data at speeds in the tens of Gb / sec and beyond. To deserialize the data, a serial-to-parallel converter is used. As shown in FIG. 1, a conventional serial-to-parallel converter uses a significant number of high-speed flip-flop circuits and a corresponding high-speed clock tree to capture the serial data and convert it to parallel data within the device. However, at these speeds, power consumption may be an issue.[0005]More particularly, conventional serial-to-parallel converters may use a number of high-speed flip-flops to capture the ...
