Embodiment Construction
[0025] The invention provides a 1-to-N high-speed serial-to-parallel converter and a method thereof, which realize the 1-to-N high-speed serial-to-parallel conversion. The present invention will be described in detail below in conjunction with the accompanying drawings.
[0026] Such as image 3 As shown, the high-speed serial-to-parallel converter provided by the present invention includes a cyclic sequencer, N input registers A1-AN, N 2-to-1 selectors C1-CN and N output registers B1-BN.
[0027] N input registers A1~AN are serially cascaded sequentially, the serial data input from one channel is input from the input port DA1 of the first input register A1, and the output terminal QAi of the input register Ai is connected to the corresponding 2-to-1 selector Ci The first input port (lower channel), the output port of the 2-to-1 selector Ci is connected to the input port DBi of the output register Bi, and the output port QBi of the output register Bi is used as the Nith outpu...

The invention discloses a 1-way to N-way high-speed serial-to-parallel conversion method and a converter, wherein the converter includes N input registers, N 2-to-1 selectors, N output registers and a cyclic sequence generator, the input register Serial cascading in sequence; the first input port of the 2-to-1 selector is connected to the corresponding input register; the input port of the output register is connected to the output port of the corresponding 2-to-1 selector, and the output port is used as the output port of the parallel data, and the ring It is connected back to the second input port of the 2-to-1 selector; the cyclic sequence generator cyclically generates a set of N-bit cyclic sequences as the output selection signal of the 2-to-1 selector. The present invention utilizes N-way 2-to-1 selectors and cascaded registers, and uses a cyclic sequence generator to generate a set of N-bit cyclic sequences to simultaneously control the 2-to-1 selectors to realize 1-way high-speed serial data sequence It is converted into N synchronous parallel data sequences, and the parallel rate is 1 / N of the serial.
Description
technical field [0001] The invention relates to the field of coherent optical communication, in particular to a high-speed serial-to-parallel conversion method and a converter. Background technique [0002] Today, coherent optical communication and optical digital signal processing technology have been widely used in the field of optical communication, and its core component, the ADC chip, plays an important role in the next generation of high-speed optical transmission systems. A high-speed, more flexible, and lower-power coherent optical receiving system can be realized through a high-speed ADC chip. But at present, the backwardness of domestic high-speed ADC chip technology and the lack of devices have greatly restricted the development of 100G optical transmission commercial equipment and the research on key technologies of post-100G optical transmission. Therefore, it is of great significance to study the core technology of ultra-high-speed ADC and promote the developm...
