STP Output Drive and Parallel Input

DC Electrical Characteristics (continued)

(VAVDD = VDVDD = 1.7V to 1.9V, VIOVDD = 1.7V to 3.6V, RL = 100Ω ±1% (differential), EP connected to PCB ground (GND), TA = -40°C

to +105°C, unless otherwise noted. Typical values are at VAVDD = VDVDD = VIOVDD = 1.8V, TA = +25°C.) (Note 3)
