摘要： A system comprising: a first integrated circuit device having a multi-band transmission circuit; second and third integrated circuit devices having respective multi-band reception circuits; and a signaling link including a first stub coupled to the multi-band transmission circuit to receive a multi-band signal therefrom, second and third stubs coupled to the multi-band reception circuits of the second and third integrated circuit devices, respectively, to deliver the multi-band signal thereto, and a plurality of channel segments that extend between the first, second and third stubs to convey the multi-band transmission signal therebetween, and wherein at least one of a physical length, impedance or propagation constant of at least one of the first stub, second stub, third stub or channel segment of the plurality of channel segments is selected to spectrally position a frequency- interval exhibiting attenuated frequency response on the signaling link such that multiple passbands separated by the frequency-interval are established to enable conveyance of the multi-band transmission signal on the signaling link.

摘要： A receiver includes simple, effective margining circuitry to support manufacturer and in-situ margin testing of high-speed communication channels. The receiver includes an input pad coupled to a termination resistor and the input of a sampler. An internal or external current source alters the current through the termination resistor to vary the DC component of the input signal applied to the input of the sampler. The voltage margins of the receiver may be tested by monitoring the output of the sampler in response to a known data stream while adjusting the voltage on the input node of the sampler to determine the degree of voltage offset that can be tolerated without inducing receive errors.
