Ethernet Interface via PHY
The useable Ethernet interface via PHY is divided in connector, transformer (magnetics) and
Ethernet PHY (see Figure 7).
Figure 7: Ethernet interface
The shielded RJ45 connector X304 is a standard Ethernet interface. It is compatible with
10BASE-T and 100BASE-TX Ethernet according to IEEE 802.3 [1] and can be connected to a
twisted pair medium such as CAT5 cable infrastructure.
Beside the RJ45 connector, SHDSL.EVB.4CH provides the possibility to use the pin header
X302 spaced 2.54 millimeters (0.1in). Table 3 gives the pin definition.

The pin header X302 is not mounted by default. It is possible to mount it on both PCB sides to
get an easy test adapter for evaluation or to use the SHDSL.EVB.4CH as module (see
chapter 7).
The transformer L302 connects the connector to the Ethernet PHY GPY112 V201 (PEF7072).
The connection to the SHDSL data pump Intel
®
SHDSL Chipset V101 is realized via standard
MII interface.
Figure 8 shows the schematic of the Ethernet interface via PHY.
