Note 4: “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.
Note 5: 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 6: Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except V_OD and
ΔV_OD.
Note 7: Typical values represent most likely parametric norms for V_CC = +3.3V and T_A = +25°C, and at the Recommended Operation Conditions at the time of
product characterization and are not guaranteed.
Note 8: Output short circuit current (I_OS) is specified as magnitude only, minus sign indicates direction only.
Note 9: Specification is guaranteed by characterization and is not tested in production.
Note 10: t_SKD1, |t_PLHD − t_PHLD|, is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of
the same channel.
Note 11: t_SKD2, Part to Part Skew, is defined as the difference between the minimum and maximum specified differential propagation delays. This specification
applies to devices at the same V_CC and within 5°C of each other within the operating temperature range.
Note 12: Measured on a clock edge with a histogram and an acummulation of 1500 histogram hits. Input stimulus jitter is subtracted geometrically.
Note 13: Tested with a combination of the 1100000101 (K28.5+ character) and 0011111010 (K28.5- character) patterns. Input stimulus jitter is subtracted
algebraically.
Note 14: Measured on an eye diagram with a histogram and an acummulation of 3500 histogram hits. Input stimulus jitter is subtracted.
