1. DETAILED DESCRIPTION
The DS3151 (single), DS3152 (dual), DS3153 (triple), and DS3154 (quad) LIUs perform the functions necessary
for interfacing at the physical layer to DS3, E3, or STS-1 lines. Each LIU has independent receive and transmit
paths and a built-in jitter attenuator. The receiver performs clock and data recovery from a B3ZS- or HDB3-coded
alternate mark inversion (AMI) signal and monitors for loss of the incoming signal. The receiver optionally performs
B3ZS/HDB3 decoding and outputs the recovered data in either binary or bipolar format. The transmitter accepts
data in either binary or bipolar format, optionally performs B3ZS/HDB3 encoding, and drives standard pulse-shape
waveforms onto 75 coaxial cable. The jitter attenuator can be mapped into the receiver data path, mapped into
the transmitter data path, or be disabled. The DS315x LIUs conform to the telecommunications standards listed in
Table 1-A
.
Figure 1-1
shows the external components required for proper operation.
