and Cable Driver
_______________________________________________________________________________________ 3
Note 1: Equalizer and driver total currents (equalizer with maximum equalization and driver with maximum output swing).
Note 2: Input voltage within specification limits, 50Ω to V
CC
at each output.
Note 3: Minimum cable input for LOS to assert high.
Note 4: 100kΩ load to ground.
Note 5: AC electrical characteristics are guaranteed by design and characterization.
Note 6: V
