General Information 1-11

Fuse Element: The +5V supplied to the front panel connectors is protected

by a Positive Temperature Coefficient (PTC) resistor. It

resets automatically when the overload is removed.

Local I

C Channel: The Eclipse3 uses I

C, a 2 wire serial bus, to control the

following on-board devices:

THC63DV164 DVI transmitter (optional)

LM75 thermal sensor (optional)

AT24C02 2 Kb serial EEPROM (optional)

DDC2B display monitor control

Power-management: With the proper software, the Borealis can power-down

unused functions and the VESA standard DDC2B lines

control the monitor.

PCI Bus Access: Programmable Bus Address Registers (BARs) in the

Borealis map control and drawing engine registers, and

display memory through its 33/66 MHz PCI interface.

PCI bus Interrupts: The Borealis can interrupt the PCI bus on the INTA line.

Bus Loading: One PCI 2.1 compatible load

Module Size: PMC: IEEE 1386-2001,

149 mm x 74 mm, 32-bit, 33/66 MHz, J1/J2

CompactPCI: PICMG 2.0 Rev 3, IEEE 1101.10,

3U form factor w/ ESD strip,

32-bit, 33/66 MHz, J1 only, no hotswap.

3U and 6U front panel options.

Optional rear-panel module connecting to

CPCI J2 is standard 3U rear I/O format.

3U and 6U rear panel options.

PCI: short PCI, 32-bit, 33/66 MHz, 64-bit

connector set is used for improved power

and ground distribution

PCI Subsystem Vendor ID: 0x10F0 (CW Vendor Code)

PCI Subsystem Device ID: 0x0003 for 16 MB boards, 0x0007 for 32 MB boards

Power Requirements: Standard versions REQUIRE that the PMC, CompactPCI,

or PCI bus connectors supply both +5V and +3.3V. A

location for a local 3.3V regulator is provided on the PMC

and PCI boards for systems which do not supply 3.3V to

the backplane.

+5V +/- 5%, 0.2 A max

+3.3V +/- 5%, 1.2 A max

PCI Bus pin PRSNT1# is set low, indicating 7.5W max.
