ELECTRICAL CHARACTERISTICS (continued)
(V
otherwise noted.) (Notes 1, 2)
Note 1: AC characterization is performed using the circuit in Figure 2 using a PRBS 2
Note 2: Specifications at -40°C are guaranteed by design and characterization.
Note 3: Excluding I
Note 4: Power-supply noise rejection (PSNR) = 20log
Note 5: The minimum required voltage at the OUT+ and OUT- pins is +0.75V.
Note 6: Guaranteed by design and characterization.
Note 7: Tested with 00001111 pattern at 2.7Gbps.
Note 8: DJ includes pulse-width distortion (PWD).
