ELECTRICAL CHARACTERISTICS (continued)
(V CC = +2.97V to +3.63V, CML output load is 50Ω to V CC , T A = -40°C to +85°C, unless otherwise noted. Typical values are at V CC =
3.3V, T A = +25°C, unless otherwise specified. The data input transition time is controlled by 4th-order Bessel filter with f -3dB = 0.75 x
2.667GHz for all data rates of 2.667Gbps and below, and with f -3dB = 0.75 x 3.2GHz for a data rate of 3.2Gbps.)
