Figure 8: LIN Molex connector
For flexibility, the LIN transceiver is also connected to a standard 0.1 in. connector (P3) at the top side
of the PCB as shown in
Figure 9 . For ease of use, the 12 V EVB supply is fed to pin1 of P3 and the
LIN transceiver power input to pin2. This allows the LIN transceiver to be powered directly from the
EVB supply by simply linking pins 1 and 2 of connector P3 using a 0.1 in. jumper shunt.
Figure 9: LIN 4pin header interface connector
By default the LIN interface is not enabled. To enable the LIN interface the jumpers detailed in
Table 4 need to be placed.

J15 LIN_EN LIN PHY (U50) enable
J16 LIN_RX LIN RX enable
J17 LIN_TX LIN TX enable
3.5 Ethernet Configuration
The EVB is fitted with a standard RJ45 Ethernet connector (J7) and a DP83848C 10/100
Ethernet transceiver (U6).
By default, the Ethernet interface is enabled. The Ethernet interface the jumpers are detailed in
