(6) Differential signal amplitude at the transmitter output providing < 1x10^–12 bit error rate. Measured at 10.3125 Gbps with a PRBS-31 data
pattern. Input transmission channel is 40-inch long FR-4 stripline, 4-mil trace width.
(7) Differential signal amplitude at the transmitter output providing < 1x10^–12 bit error rate. Measured at 10.3125 Gbps with a PRBS-31 data
pattern. Input transmission channel is 30-inch long FR-4 stripline, 4-mil trace width.
(8) Differential signal amplitude at the transmitter output providing < 1x10^–12 bit error rate. Measured at 10.3125 Gbps with a PRBS-31 data
pattern. No input transmission channel.
(9) Measured with 10-MHz clock pattern output.
(10) Measured with clock-like {11111 00000} pattern.
(11) Slew rate is controlled by SMBus register settings.
(12) Typical at 10.3125-Gbps bit rate.
(13) De-emphasis pulse width varies with V_OD and de-emphasis settings.
(14) Typical with no output de-emphasis, minimum output transmission channel.
