DETAILED DESCRIPTION The DS3181 (single), DS3182 (dual), DS3183 (triple), and DS3184 (quad) PHYs perform all the functions necessary for mapping/demapping ATM cells and/or packets into as many as four DS3 (44.736Mbps) framed, E3
(34.368Mbps) framed, or 52Mbps clear-channel data streams on DS3, E3, or STS-1 physical copper lines. Each line interface unit (LIU) has independent receive and transmit paths. The receiver LIU block performs clock and
data recovery from a B3ZS- or HDB3-coded AMI signal and monitors for loss of the incoming signal or can be bypassed for direct clock and data inputs. The receiver LIU block optionally performs B3ZS/HDB3 decoding. The
transmitter LIU drives standard pulse-shape waveforms onto 75� coaxial cable or can be bypassed for direct clock and data outputs. The jitter attenuator can be placed in either transmit or receive data path when the LIU is enabled. Dedicated cell processor and packet processor blocks prepare outgoing cells or packets for transmission
and check incoming cells or packets upon arrival. Built-in DS3/E3 framers transmit and receive cell/packet data in properly formatted M23 DS3, C-bit DS3, G.751 E3, or G.832 E3 data streams. PLCP framers provide legacy ATM
transmission-convergence support. DSS scrambling is performed for clear-channel ATM cell support. With integrated hardware support for both cells and packets, the DS318x DS3/E3 ATM/Packet PHYs provide system on-
chip solutions (from DS3/E3/STS-1 physical copper lines to ATM/Packet UTOPIA/POS-PHY Level 2/3 system switch) for universal high-density line cards in the unchannelized DS3/E3/clear-channel DS3 ATM/Packet
applications. Unused functions can be powered down to reduce device power. The DS318x ATM/Packet PHYs with embedded LIU conform to the telecommunications standards listed in Section 4.
