GX4002 Datasheet, PDF (9/74 Pages) Gennum Corporation – Dynamic on-chip power management control

Table 2-1: DC Electrical Characteristics (Continued)
V_CC = +2.8V to +3.47V, T_C = -40°C to 100°C. Typical values are V_CC = +3.3V and T_A = 25°C, unless otherwise specified.
Specifications assume default setting to end-terminated 50Ω transmission lines, unless otherwise stated. Typical Data Rate = 14.025Gb/s
Note: mApp refers to mA peak-to-peak value.
