(1) The Electrical Characteristics tables list verified specifications under the listed Recommended Operating Conditions except as otherwise
modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not
verified.
(2) Typical values represent most likely parametric norms at V_DD = 2.5V, T_A = 25°C., and at the Recommended Operation Conditions at the
time of product characterization and are not verified.
(3) Measured at package pins of receiver. The 130 mVp-p is a typical threshold level and does not include hysteresis, thus less than 40
mVp-p is IDLE, greater than 175 mVp-p is ACTIVE. SD_TH pin connected with resistor to GND overrides this default setting.
(4) Measured with clock-like {11111 00000} pattern.
