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, 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 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.
