TRANSMIT PATH LINE INTERFACE
The transmit path of the XRT83SH38 LIU consists of 8 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 16

TCLK/TPOS/TNEG Digital Inputs
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 XRT83SH38 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 17
is a timing diagram of the transmit input
data sampled on the falling edge of TCLK.
Figure 18
is a timing diagram of the transmit input data sampled on
the rising edge of TCLK. The timing specifications are shown in
Table 7
