Methods and systems for performing built-in-self-test operations without a dedicated clock source

A receiver system for performing a Built-In-Self-Test (BIST) operation, the receiver system configured to:

• perform a first BIST operation to receive, by a first receiver lane of the receiver system that is configured to receive transmitted data from a first lane via one or more first input terminals, a first transmitter (TX) clock from a second receiver lane of the receiver system that is configured to receive transmitted data from a second lane via one or more second input terminals, wherein the second receiver lane is configured to function as a synthesized clock source;
• transmit, by a transmitter component of the first receiver lane, a test data sequence, wherein the test data sequence is generated based on a test data pattern and the first TX clock;
• and
• determine, by the first receiver lane, that the first BIST operation is successful if a received data sequence, received by at least one receiver component of the first receiver lane, is matching the test data sequence transmitted by the transmitter component.

A method for performing Built-In-Self-Test (BIST) operations, the method comprising:

• performing a first BIST operation by receiving, by a plurality of receiver lanes of a receiver system configured to receive transmitted data from a first lane via one or more first input terminals, a transmitter (TX) clock from a separate receiver lane of the receiver system, wherein the separate receiver lane of the receiver system is configured to receive transmitted data from a second lane via one or more second input terminals, wherein the second receiver lane is configured to function as a clock source;
• transmitting, by transmitter components in each of the plurality of receiver lanes, test data sequences, wherein the test data sequences are generated based on a test data pattern and the TX clock;
• and
• determining whether the BIST operations performed by each of the plurality of receiver lanes are successful if received data sequences, received by at least one receiver component in each of the plurality of receiver lanes, is matching the test data sequences transmitted by the transmitter components in each of the plurality of receiver lanes.
