RNEG/LCV_OF Output
In dual rail mode, this pin is the receive negative data output. In single rail
mode, this pin is a Line Code Violation / Counter Overflow indicator. If LCV is
selected by programming the appropriate global register and If a line code vio-
lation, 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 saturated. 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.
