CML RECEIVER DC SPECIFICATIONS (RIN+, RIN-)
(1) The Electrical Characteristics tables list ensured 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 ensured.
(2) Current into device pins is defined as positive. Current out of a device pin is defined as negative. Voltages are referenced to ground
except VOD, ΔVOD, VTH and VTL which are differential voltages.
(3) Typical values represent most likely parametric norms at 1.8V or 3.3V, T
A
= +25°C, and at the Recommended Operation Conditions at
the time of product characterization and are not ensured.
