RECEIVE PATH LINE INTERFACE
The receive path of the XRT83VSH316 LIU consists of 16 independent T1/E1/J1 receivers. The following
section describes the complete receive path from RTIP/RRING inputs to RCLK/RPOS/RNEG outputs. If any of
the diagnostic detection features are used, the LIU must be set in Single Rail mode. Since, the receive path
has system 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 receive and transmit path is shown in
Figure 3

3.1.1
The input stage of the receive path accepts standard T1/E1/J1 twisted pair or E1 coaxial cable inputs through
RTIP and RRING. The physical interface is optimized by placing the terminating impedance inside the LIU.
This allows one bill of materials for all modes of operation reducing the number of external components
necessary in system design. The receive termination impedance (along with the transmit impedance) is
selected by programming TERSEL[1:0] to match the line impedance. Selecting the internal impedance is
shown in
Table 2
