TRANSMIT PATH LINE INTERFACE
The transmit path of the XRT83SL28 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 12.
2.1
In dual rail mode, TPOS and TNEG are the digital inputs for the transmit path. In single rail mode, TNEG can
be tied to ground unless Hardware mode is selected (see the Hardware Pin Description). The XRT83SL28 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 TCLKinv to "1" in the appropriate global register.
Figure 13 is a timing diagram of the transmit input data sampled on the falling edge of TCLK. Figure 14 is a
timing diagram of the transmit input data sampled on the rising edge of TCLK. The timing specifications are
shown in Table 3.
