Note 9:
Isolation test: three channels driven with identical 3.2Gbps PRBS with maximum input signal to each equalizer and maxi-
mum input signal on driver. The measured channel meets the residual and random jitter specifications with an uncorrelated
3.2Gbps PRBS data at minimum input signal level on equalizer and maximum signal level on driver.
Note 10:
Equalizer time constant measured from data on to closed-loop operation.
