The receiver is designed so that the LIU can recover clock and data from an attenuated line signal caused by
cable loss or flat loss according to industry specifications. Once data is recovered, it is processed and
presented at the receiver outputs according to the format chosen to interface with a Framer/Mapper or ASIC.
This section describes the detailed operation of various blocks within the receive path. A simplified block
diagram of the receive path is shown in Figure 6.

Physical Layer devices are AC coupled to a line interface through a 1:1 transformer. The transformer provides
isolation and a level shift by blocking the DC offset of the incoming data stream. The typical medium for the
line interface is a 75
coxial cable. Whether using E3, DS-3 or STS-1, the LIU requires the same bill of
materials, see Figure 7.
