4.6. Serial Interprocessor Interface (SIPI)
A dedicated SIPI interface connector is provided on the daughter card. For signal integrity the SIPI
signals are not routed to the mother board. Test points are provided on the signals so they can be
accessed if required to be used as a different function.
A 10 pin Samtec connector (J17: ERF8-005-05.0-LDV-L-TR) is used for the SIPI interface. The pin-out
of the connector is shown in Figure 18.
