面向StratixII千兆接收器通道的“字对齐”设计技术

Design Technology of Word Alignment for Receiver Channel(1Gbps) in Stratix II Device

ALTERA公司StratixII器件的接收器通道没有像Stratix GX EP1SGX40G那样有"字对齐"功能。为此,专门设计了"字对齐器",其中含有字对齐引擎和COMMA检测电路,附加在片内的接收器上,即可自动完成"字对齐"的功能。经仿真,达到了预期的效果。

Stratix GX EP1SGX40G of ALTERA Company has Word alignment function, but Stratix II receiver channel does not have. Therefore, a Word-aligner, which contains word alignment engine and COMMA detector circuitry, is designed to help the receiver channel perform the function of Word alignment automatically. The result of simulation proved that the design achieved our purposes.
