RNEG/LCV_OF Output
In dual rail mode, this pin is the receive negative data output. In single rail
mode, this pin can either be a Line Code Violation or Overflow indicator. If LCV
is selected by software and if a line code violation, a bi-polar violation, or
excessive zeros occur, the LCV pin will pull "High" for a minimum of one RCLK
cycle. LCV will remain "High" until there are no more violations. However, if
OF is selected the LCV pin will pull "High" if the internal LCV counter is satu-
rated. The LCV pin will remain "High" until the LCV counter is reset.

Receive Differential Tip Input
RTIP is the positive differential input from the line interface. Along with the
RRING signal, these pins should be coupled to a 1:1 transformer for proper
operation.
