EPC-3307 Hardware Reference
2
You can set up the EPC-3307 in these physical configurations:
The EPC-3307 can be fitted with a PMC module, a PCI Mezzanine card that
conforms to IEEE P1386.1. For more information about PMC modules, see
Appendix F, PMC modules
.
Feature summary
The EPC-3307 is a CompactPCI, peripheral processor board designed around the
Intel PIII BGA2 mobile processor and the GX/PIIX4E chipset. As a peripheral
processor, the EPC-3307 typically operates in a peripheral slot of a CompactPCI
backplane. It can operate in a System Slot, but the EPC-3307 does not provide
clocking, arbitration, or bus enumeration.
The Intel 21554, a non-transparent PCI-to-PCI bridge, allows operation in a
peripheral slot. The H.110 telephony bus interface, supplied by the Lucent T8105,
provides for transfer of telephony data from the H.110 bus to PMC Site A (J13).
The EPC-3307 uses both soldered-down SDRAM and a RadiSys custom memory
module. The Intel GX chipset allows the use of 256mbit SDRAM components.
The EPC-3307 board includes:
•
BGA2 Pentium III processor
: Runs at 700 MHz and includes a 100 MHz Front
Side Bus plus a 256kbyte on-die cache.
•
GX North Bridge
: Includes a 100 MHz memory bus and a 33MHz, 32-bit local
PCI bus. It supports 256 Mbit SDRAMS but does not use the AGP Graphics port.
•
Intel South Bridge PIIX4E chip
: This PCI-to-ISA bridge includes two
independent EIDE channesl and battery-backed real-time clock.
•
64-bit CompactPCI interface
: Located on J1/J2, this interface uses Intel 21554
non-transparent PCI bridge with I/O slot compatibility.
•
Lucent T8105 Time-slot interchanger
: Provides H.110 to PMC interface,
accepts local streams to/from RadiSys Tempest PMC, and accepts local streams
from RadiSys Hornet PMC (not validated).
When configuring ...
You can add one of these options...
PMC slot 1
• A hard disk drive.
• One PMC (including the RadiSys Tempest TDM PMC).
PMC slot 2
• One PMC.
• Up to 2 memory modules.
The EPC-3307 does not require a RadiSys-manufactured PMC. The EPC-3307
can accept most PMC types excluding those that either require a disk BIOS in
the EPC or do not fit by form factor.
