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 V
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: Allowed supply noise (mV
Note 5: Specification is guaranteed by characterization at optimal boost setting and is not tested in production.
Note 6: Deterministic jitter is measured at the differential outputs (point C of Figure 1), minus the deterministic jitter before the test channel (point A of Figure 1).
Random jitter is removed through the use of averaging or similar means.
Note 7: Measured with clock-like {11111 00000} pattern.
Note 8: Random jitter contributed by the equalizer is defined as sqrt (J
