4. DETAILED DESCRIPTION
The DS32506 (6 port), DS32508 (8 port), and DS32512 (12 port) 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 (NRZ) or digital bipolar format. The
transmitter accepts data in either binary (NRZ) or digital bipolar format, optionally performs B3ZS/HDB3 encoding,
and drives standard pulse-shape waveforms onto 75
Ω coaxial cable. Both transmitter and receiver are high-
impedance when VDD is out of spec to enable hot-swappable 1:1 and 1+1 board redundancy without relays. The
jitter attenuator can be mapped into the receiver data path, mapped into the transmitter data path, or disabled. An
on-chip clock adapter generates all line-rate clocks from a single input clock. Control interface options include 8- or
16-bit parallel, SPI, and hardware mode. The DS325xx LIUs conform to the telecommunications standards listed in
Table 1-1. The external components required for proper operation are shown in Figure 4-1 and Figure 4-2.
