Share the same I/O pins with other connectors:
The HSTC connector group HSTCA (J1, J2) and HSTCB (J3, J4) share the same I/O pins with
the GPIO expansion headers (J13, J14) and DDR2 SO-DIMM socket (J9), respectively. Hence
none of the combinations above is allowed to be used at the same time.
Power Supply:
The HSTC connector provides 12, 5, and 3.3 volt for power supply purpose. There are also two
power input pin named B<HSTC Group>_VTT and B<HSTC Group>_VREF, which are
connected to the input reference voltage(V
REF
) and termination voltage pin (V
TT
) of the Stratix
III FPGA, respectively.
Finally,
Table A-6
to
Table A-11
shows the connections between the HSTC connectors and the
FPGA.
