Carrier card design
Appendix G
To use Monarch mode, you must design a carrier card that supports Monarch
mode. The rest of this appendix provides guidelines for designing such a card.
PrPMC connectors (Jn1 and Jn2)
General
Leave all reserve pins unconnected.
The PCI:~RST signal is an input to the PrPMC. It requires a pullup (1K to +3.3V)
for the EPC-6315 to operate properly.
Power
The EPC-6315 includes the following power considerations: +5V, +3.3V, +12V,
–12V, and VI/O.
VCC and +3.3V requires:
•
A single bulk bypass near the power connection to the EPC-6315.
•
A high-frequency decoupling cap at each pin.
+12 and –12V are not used on the board and only require the high-frequency
decoupling cap.
VI/O requires a a high-frequency decoupling cap on each pin. VI/O can be either
+5V or +3.3V.
PCI
Design interrupt and IDSEL routing to match the
PCI-to-PCI Bridge Architecture
Specification Revision 1.1
.
The ~LOCK, ~SDONE, and ~SBO signals are not used; you can leave them
unconnected.
Tie JTAG signals to an inactive state. That is, TCK and ~TRST low and TMS and
TDI high. Leave TDO unconnected.
Tie ~BUSMODE1 and ~BUSMODE2 through a resistor to VI/O. ~BUSMODE3/NC
and ~BUSMODE4/NC can be left unconnected. Although the PrPMC specification
requires that these have 10K Ohm pull-down resistors, these are not required for
~BUSMODE3/NC and ~BUSMODE4/NC.
~REQ64 and ~ACK64 should be bussed and tied through a resistor to VI/O.
