  • Circuitry on an integrated circuit for performing or facilitating oscilloscope, jitter, and/or bit-error-rate tester operations
    Patent number: 8504882
    Abstract: An integrated circuit (“IC”) includes circuitry for use in testing a serial data signal. One such IC includes circuitry for transmitting the serial data signal with optional jitter, optional noise, and/or controllably variable drive strength. One such IC also includes circuitry for receiving the serial data signal and performing a bit error rate (“BER”) analysis in such a signal. Such an IC provides output signals indicative of results of its operations. One such IC operates in various modes to perform or at least emulate functions of an oscilloscope, a bit error rate tester, etc., for testing signals and circuitry with respect to jitter-tolerance, noise-tolerance, etc.
