REV. 1.0.4
THREE CHANNEL E3/DS3/STS-1 LINE
NOTES:
1.
When Dual-Rail data format is selected, the B3ZS/HDB3 Encoder is automatically disabled.
2.
In Dual-Rail format, the Bipolar Violations in the incoming data stream is converted to valid data pulses.
3.
Encoder and Decoder is enabled only in Single-Rail mode.
5.3
TRANSMIT PULSE SHAPER:
The Transmit Pulse Shaper converts the B3ZS encoded digital pulses into a single analog Alternate Mark
Inversion (AMI) pulse that meet the industry standard mask template requirements for STS-1 and DS3. See
Figures 8 and 9.
For E3 mode, the pulse shaper converts the HDB3 encoded pulses into a single full amplitude square shaped
pulse with very little slope. This is illustrated in Figure 7.
The Pulse Shaper Block also includes a Transmit Build Out Circuit, which can either be disabled or enabled by
setting the TxLEV_n input pin “High” or “Low” (in Hardware Mode) or setting the TxLEV_n bit to “1” or “0” in the
control register (in Host Mode).
For DS3/STS-1 rates, the Transmit Build Out Circuit is used to shape the transmit waveform that ensures that
transmit pulse template requirements are met at the Cross-Connect system. The distance between the
transmitter output and the Cross-Connect system can be between 0 to 450 feet.
For E3 rate, since the output pulse template is measured at the secondary of the transformer and since there is
no Cross-Connect system pulse template requirements, the Transmit Build Out Circuit is always disabled.
5.3.1
Guidelines for using Transmit Build Out Circuit:
If the distance between the transmitter and the DSX3 or STSX-1, Cross-Connect system, is less than 225 feet,
enable the Transmit Build Out Circuit by setting the TxLEV_n input pin “Low” (in Hardware Mode) or setting the
TxLEV_n control bit to “0” (in Host Mode).
If the distance between the transmitter and the DSX3 or STSX-1 is greater than 225 feet, disable the Transmit
Build Out Circuit.
5.3.2
Interfacing to the line:
The differential line driver increases the transmit waveform to appropriate level and drives into the 75
load as
shown in Figure 6.
