_______________________________________________________________________________________
Typical Operating Characteristics
(VCC = +3.3V, 3.125Gbps, 500mVp-p cable input with 27 - 1 PRBS, TA = +25°C, unless otherwise noted. Note: Twin-axial cable
used was Tensolite, Z-Skew, 100
Ω, 28AWG. Shielded twisted pair used was Madison 100Ω, 30AWG, spec #14887.)
