(5) 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.
(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 30-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. No input transmission channel.
(8) Measured with 10 MHz clock pattern output.
(9) Measured with clock-like {11111 00000} pattern.
(10) Slew rate is controlled by SMBus register settings.
(11) Typical at 10.3125 Gbps bit rate.
(12) De-emphasis pulse width varies with V_OD and de-emphasis settings.
