E3/DS3/STS-1 LINE INTERFACE UNIT
REV. 1.0.2
Figure 11 illustrates the typical interface for the transmission of data in a Dual-Rail Format between the
Terminal Equipment and the Transmit Section of the XRT73LC00A.
The manner that the LIU handles Dual-Rail data is described below and illustrated in Figure 12.
The
XRT73LC00A typically samples the data on the TPDATA and TNDATA input pins on the falling edge of TCLK.
TCLK is typically a clock signal that is of the selected data rate frequency. For the E3 data rate, TCLK is
34.368 MHz. For the DS3 data rate, TCLK is 44.736 MHz and for the SONET STS-1 rate, TCLK is 51.84 MHz.
In general, if the XRT73LC00A samples a “1” on the TPDATA input pin, the Transmit Section of the device
ultimately generates a positive polarity pulse via the TTIP and TRING output pins across a 1:1 transformer. If
the XRT73LC00A samples a “1” on the TNDATA input pin, the Transmit Section of the device ultimately
generates a negative polarity pulse via the TTIP and TRING output pins across a 1:1 transformer.
2.1.1
Accepting Single-Rail Data from the Terminal Equipment
Do the following if data is to be transmited from the Terminal Equipment to the XRT73LC00A in Single-Rail
format (a binary data stream) without having to convert it into a Dual-Rail format.
A. Configure the XRT73LC00A to operate in the HOST Mode or,
