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 operation
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 operation
and 2KΩ pull up otherwise.
Positive CMLOutput Channel C with internal 50Ω pull up during normal operation and
2KΩ pull up otherwise.
Negative CMLOutput Channel C with internal 50Ω pull up during normal operation
and 2KΩ pull up otherwise.
Positive CMLOutput Channel D with internal 50Ω pull up during normal operation and
2KΩ pull up otherwise.
Negative CMLOutput Channel D with internal 50Ω pull up during normal operation
and 2KΩ pull up otherwise.
EN_[A:D] is the enable pin with internal 50KΩ pull up resistor. A LVCMOS high
provides normal operation. A LVCMOS low selects a low power down mode.
