XRT73LC00A is to take TTL/CMOS level data from
the terminal equipment and encode it into a format
that can:
1.
be efficiently transmitted over coaxial cable at E3,
DS3 or STS-1 data rates.

4.
The on-chip Pulse-Shaping circuitry is configured
to generate Transmit Output pulses of the correct
shape and width to meet the applicable pulse
template requirement.
5.
The LOS Declaration/Clearance Criteria is estab-
lished.

Figure 1 indicates that the Transmit Section of the
XRT73LC00A consists of the following blocks:
Transmit Logic Block
Duty Cycle Adjust Block
HDB3/B3ZS Encoder
Pulse Shaping Block
The purpose of the Transmit Section in the
THE TRANSMIT SECTION
2.
be reliably received by the Remote Terminal at
the other end of the E3, DS3 or STS-1 data link.
3.

The purpose of the Transmit Logic Block is to accept
either Dual-Rail or Single-Rail (a binary data stream)
TTL/CMOS level data and timing information from the
Terminal Equipment.
Accepting Dual-Rail Data from the Terminal
Equipment
The XRT73LC00A accepts Dual-Rail data from the
Terminal Equipment via the following input signals:
TPDATA
TNDATA
TCLK
Figure 11 illustrates the typical interface for the trans-
mission of data in a Dual-Rail Format between the
Terminal Equipment and the Transmit Section of the
XRT73LC00A.
