Using the LSI20860
The component height on the top and bottom of the board conforms to
the PCI Specification.
1.1.2.2 Electrical Characteristics
The LSI20860 maximum power requirement, including SCSI TERMPWR,
under normal operation is:
Under abnormal conditions such as a short on SCSI TERMPWR, +5 V
current may be higher. At temperatures of at least 25
°
C a current of
4 A is sustained no longer than 30 seconds before the self-resetting
TERMPWR short circuit protection device opens.
The PCI
PRSNT1/
and
PRSNT2/
pins are set to indicate a 7.5 W
maximum configuration.
1.1.2.3 Thermal, Atmospheric Characteristics
The board is designed to operate in an environment defined by the
following parameters:
•
Temperature range: 5
°
C to 55
°
C (dry bulb)
•
Relative humidity range: 5% to 90% noncondensing
•
Maximum dew point temperature: 32

1.1.2.4 Electromagnetic Compliance
The board is designed and implemented to minimize electromagnetic
emissions, susceptibility, and the effects of electromagnetic discharge.
The board meets the requirements of FCC Class B and CISPR 22 limits
and is marked with the FCC Class B Declaration of Conformity Symbol.
It also carries the CE mark.
