3 Interfaces
This chapter describes the interfaces and header pinouts of the SHDSL.EVB.4CH Evaluation
Board.
3.1 Design Overview
The design with its main function blocks and important components are shown in Figure 4. The
description for it is given in the following section.

3.2 SHDSL Interface
The SHDSL interface is divided in SHDSL connector, SHDSL Transformer, Protection, Hybrid
and SHDSL data pump (see Figure 5).

Additional primary protection is necessary depending on requirements. There is no primary
protection on the evaluation board available.
The connector X107 is an unshielded RJ45 connector. It is used for connecting the
SHDSL.EVB.4CH up to four SHDSL lines (according ITU-T G.991.2 [3]). Table 1 shows the
pin definition of X107.
