    摘要: An integrated circuit (IC), comprises a receiver on an IC substrate. The receiver is configured to receive a stressed input signal. A built in self test (BIST) circuit is provided on the IC substrate for testing the receiver. The BIST circuit comprises an encoder configured for receiving an input signal and identifying whether a first condition is present, in which two or more consecutive input data bits have the same polarity as each other. An output driver circuit provides the stressed input signal corresponding to the two or more consecutive input data bits. The stressed input signal has an amplitude that is larger when the encoder identifies that the first condition is present and smaller when the encoder identifies that two or more consecutive input data bits have different polarity from each other.

    摘要: A squelch detector includes a first circuit, a second circuit, and a comparator. The first circuit is configured to receive a first pair of differential input signals and in response output a second pair of differential signals. The second pair of differential signals have higher voltages than the first pair of differential input signals. The second circuit is coupled to the first circuit and is configured to extract first and second voltage levels from the second pair of differential signals. The comparator is configured to output a squelch level signal based on a comparison of the first voltage level and a third voltage level. The third voltage level is based on the second voltage level and a reference voltage.

    摘要: A voltage swing decomposition circuit includes first and second clamp circuits and a protection circuit. The first clamp circuit is configured to clamp an output node of the first clamp circuit at a first voltage level when an input node of the voltage swing decomposition circuit has a voltage higher than the first voltage level. The second clamp circuit is configured to clamp an output node of the second clamp circuit at a second voltage level, higher than the first level, when the voltage of the input node is lower than the second voltage level. The protection circuit is coupled to the output nodes of the first and second clamp circuits, and is configured to selectively set an output node of the protection circuit to the first or second voltage level. The first and second clamp circuits are coupled together by the output node of the protection circuit.
