(3) 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 ensured.
(4) 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 ensured.
(5) Measured at package pins of receiver. Less than 65 mVp-p is IDLE, greater than 175 mVp-p is ACTIVE. SD_TH pin connected with
resistor to GND overrides this default setting.
(6) Measured with clock-like {11111 00000} pattern.
