1.8V Supply Voltage
Positive CML Input Channel A with internal 50Ω pull down
Negative CML Input Channel A with internal 50Ω pull down
Supply Ground
Positive CML Input Channel B with internal 50Ω pull down
Negative CML Input Channel B with internal 50Ω pull down
Selection pins for equalizer (see Amplifi er Confi guration Table)
w/ 50KΩ internal pull up
Selection pins for amplifi er (see Amplifi er Confi guration Table)
w/ 50KΩ internal pull up
Selection pins for De-Emphasis (See De-Emphasis Confi guration Table)
w/ 50KΩ internal pull up
Positive CML Output Channel A internal 50Ω pull up during normal operation and
2KΩ pull up otherwise.
Negative CML Output Channel A with internal 50Ω pull up during normal opera-
tion and 2KΩ pull up otherwise.
Positive CML Output Channel B with internal 50Ω pull up during normal operation
and 2KΩ pull up otherwise.
Negative CMLOutput Channel B with internal 50Ω pull up during normal opera-
tion and 2KΩ pull up otherwise.
EN_[A:B] is the enable pin. A LVCMOS high provides normal operation. A LVC-
MOS low selects a low power down mode.

Signal Detect, output for channels A and B. Provides a LVCMOS high output when
a valid input signal is detected. When low, SD_X indicates that the input signal
level is below the signal detect threshold level.
