ELECTRICAL CHARACTERISTICS
(V
CC
= 2.85V to 3.63V, T
A
= -40°C to +85°C, CML receiver output load is AC-coupled to differential 100
Ω, C
AZ
= 1nF, transmitter out-
put load is AC-coupled to differential 100
Ω (see Figure 1), typical values are at +25°C, V
CC
= 3.3V, I
BIAS
= 6mA, I
MOD
= 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 RATE_SEL bit was used and the RSEL pin was left open.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
