TRANSMIT PATH LINE INTERFACE
The transmit path of the XRT83VSH316 LIU consists of 16 independent T1/E1/J1 transmitters. The following
section describes the complete transmit path from TCLK/TPOS/TNEG inputs to TTIP/TRING outputs. If any of
the diagnostic detection features are used, the LIU must be set in Single Rail mode. Since, the transmit path
has line side diagnostic generators, the part will automatically be placed in Singe Rail Mode whenever one of
the diagnostic patterns is used. A simplified block diagram of the transmit and receive path is shown in
Figure 16
