ELECTRICAL CHARACTERISTICS (continued)
(VCC = 2.85V to 3.63V, TA = -40°C to +85°C, CML receiver output load is AC-coupled to differential 100
Ω, CAZ = 1nF, transmitter out-
put load is AC-coupled to differential 100
Ω (see Figure 1), typical values are at +25°C, VCC = 3.3V, IBIAS = 6mA, IMOD = 6mA, unless
otherwise specified. Registers are set to default values unless otherwise noted, and the 3-wire interface is static during measure-
ments. For testing, the MODE_SEL bit was used and the MSEL pin was left open.)
