THREE CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT WITH JITTER ATTENUATOR
XRT75R03
REV. 1.0.7
40
FUNCTIONAL DESCRIPTION:
Figure 1 shows the functional block diagram of the device. Each channel can be independently configured
either by Hardware Mode or by Host Mode to support E3, DS3 or STS-1 modes. A detailed operation of each
section is described below.
Each channel consists of the following functional blocks:
5.0
THE TRANSMITTER SECTION:
The Transmitter Section, within each Channel, accepts TTL/CMOS level signals from the Terminal Equipment
in selectable data formats.
Convert the CMOS level B3ZS or HDB3 encoded data into pulses with shapes that are compliant with the
various industry standard pulse template requirements. Figures 7, 8 and 9 illustrate the pulse template
requirements.
Encode the un-encoded NRZ data into either B3ZS format for (DS3 or STS-1) or HDB3 format (for E3) and
convert to pulses with shapes and width that are compliant with industry standard pulse template
requirements. Figures 7, 8 and 9 illustrate the pulse template requirements.
In Single-Rail or un-encoded Non-Return-to-Zero (NRZ) mode, data is input via TPData_n pins while
TNData_n pins must be grounded. The NRZ or Single-Rail mode is selected when the SR/DR input pin is
“High” (in Hardware Mode) or bit 0 of channel control register is “1” (in Host Mode). Figure 12 illustrates the
Single-Rail or NRZ format.
In Dual-Rail mode, data is input via TPData_n and TNData_n pins. TPData_n contains positive data and
TNData_n contains negative data. The SR/DR input pin = “Low” (in Hardware Mode) or bit 0 of channel
register = “0” (in Host Mode) enables the Dual-Rail mode. Figure 13 illustrates the Dual-Rail data format.
