TRANSMIT PATH LINE INTERFACE
The transmit path of the XRT83VSH314 LIU consists of 14 independent T1/E1/J1 transmitters. The following
section describes the complete transmit path from TCLK/TPOS/TNEG inputs to TTIP/TRING outputs. A
simplified block diagram of the transmit path is shown in
Figure 13

4.1
In dual rail mode, TPOS and TNEG are the digital inputs for the transmit path. In single rail mode, TNEG has
no function and can be left unconnected. The XRT83VSH314 can be programmed to sample the inputs on
either edge of TCLK. By default, data is sampled on the falling edge of TCLK. To sample data on the rising
edge of TCLK, set TCLKE to "1" in the appropriate global register.
Figure 14
is a timing diagram of the transmit
input data sampled on the falling edge of TCLK.
Figure 15
is a timing diagram of the transmit input data
sampled on the rising edge of TCLK. The timing specifications are shown in
Table 5
