(V
CC
= 3.14V to 3.46V, T
A
= 0°C to +85°C. Typical values are at V
CC
= 3.3V and T
A
= +25°C, unless otherwise noted.)
Note 1: Equalizer total currents (equalizer with maximum equalization) and R
MOD
= 10kΩ (maximum driver swing).
Note 2: Input voltage within specification limits, 50Ω to V
CC
at each output.
Note 3: Minimum cable input for LOS_ to deassert high.
Note 4: 100kΩ load to ground. The minimum input signal level that turns off the LOS_ alarm depends on the data rate and cable
length.
Note 5: AC electrical characteristics are guaranteed by design and characterization.

-1 PRBS plus 100 consecutive ones and 100 consecutive zeros.
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 uncorre-
lated 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.
