R_S2) each ⁽²⁾, V_S = 3.3V, R_L = 100Ω differential, V_OUT = 0.8 V_PP. See DEFINITION OF TERMS AND SPECIFICATIONS
(ALPHABETICAL ORDER) for definition of terms used throughout the datasheet. Boldface limits apply at the temperature
extremes.

(1) Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very
limited self-heating of the device such that T_J = T_A. No specification of parametric performance is indicated in the electrical tables under
conditions of internal self-heating where T_J > T_A.
(2) Quiescent device common mode input voltage is 0.3V.
(3) Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using
Statistical Quality Control (SQC) methods.
(4) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped
production material.
(5) Slew Rate is the average of the rising and falling edges.
(6) Distortion data taken under single ended input condition.
(7) 0 dBm = 894 mV_PP across 100Ω differential load
