Abstract: Built-in-self-test (BIST operations are performed by receiver lanes of a multilane receiver system, wherein at least one receiver lane is configured as a synthesized clock source for other receiver lanes configured to perform BIST operations. The at least one receiver lane configured as the synthesized clock source may generate a clock signal and provide the clock signal to the other receiver lanes performing the BIST operations. In some examples, digital control signals may be used for coordinating the enablement of the at least one receiver lane to function as the synthesized clock source and for coordinating the enablement of the other receiver lanes to perform BIST operations.

Abstract: The present disclosure provides systems and methods for performing built-in-self-test (BIST) operations without a dedicated clock source. The BIST operations are performed by receiver lanes of a multilane receiver system, wherein at least one receiver lane is configured as synthesized clock source for other receiver lanes configured to perform BIST operations. The at least one receiver lane configured as the synthesized clock source may generate a clock signal and provide the clock signal to the other receiver lanes performing the BIST operations. In some examples, digital control signals may be used for coordinating the enablement of the at least one receiver lane to function as the synthesized clock source and for coordinating the enablement of the other receiver lanes to perform BIST operations.
