Abstract: In an example, a self-testing integrated circuit (IC) includes N channels i and a controller, where i is an integer from 1 to N. Each channel i may include a clock and data recovery circuit (CDR), a pseudorandom bit stream (PRBS) generator circuit, and a PRBS checker and eye quality monitor (EQM) circuit. The controller may be configured to selectively couple the channels i in a daisy chain during self-testing.
Abstract translation: 在一个示例中,自测集成电路(IC)包括N个通道i和一个控制器,其中i是从1到N的整数。每个通道i可以包括时钟和数据恢复电路(CDR),伪随机位流 (PRBS)发生器电路,以及PRBS检查器和眼睛质量监视器(EQM)电路。 控制器可以被配置为在自检期间选择性地将菊通道中的通道i耦合到菊花链中。
