TRANSMIT PATH LINE INTERFACE
The transmit path of the XRT83VSH28 LIU consists of 8 independent E1 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.

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 XRT83VSH28 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.
