Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability
and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in
the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the
device should not be operated beyond such conditions. Absolute Maximum Numbers are guaranteed for a junction temperature range of -40°C to +125°C. Models
are validated to Maximum Operating Voltages only.
Note 2: Typical values represent most likely parametric norms at VDD = 2.5V, TA = 25°C., and at the Recommended Operation Conditions at the time of product
characterization and are not guaranteed.
Note 3: The Electrical Characteristics tables list guaranteed 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 guaranteed.
Note 4: OOB signal pass-through limited to a minimum ambient temperature of -10C
Note 5: Allowed supply noise (mVP-P sine wave) under typical conditions.
Note 6: Measured with clock-like {11111 00000} pattern.
Note 7: Measured with ENSMB = 1, all channels disabled using SMBus registers 0x01 and 0x02, and EQ in bypass (Default)
Note 8: 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.
Note 9: Common-mode voltage (VCM) is expressed mathematically as the average of the two signal voltages with respect to local ground.
VCM = (A + B) / 2, A = OUT+, B = OUT-.
