3.1.2 Electrical Characteristics

The LSI21003 maximum power requirements, which include SCSI

TERMPWR, under normal operation are listed in Table 3.1:

Table 3.1 Maximum Power Requirements

+5 V DC

± 5%

1.5 A

Over the operating range 5 ° C to 55 ° C

 

 

 

 

The PCI PRSNT1# and PRSNT2# pins are set to indicate a 15 W maximum configuration.

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 3 A is sustained no longer than ten seconds before the self-resetting TERMPWR short circuit protection device opens.

3.1.3 Thermal, Atmospheric Characteristics

The board is designed to operate in an environment, which is defined by the following parameters:

Temperature range: 0 to 55 ° C (dry bulb)

Relative humidity range: 5% to 90% (noncondensing)

Maximum dew point temperature: 32 ° C

The board is designed for a storage and transit environment, which is defined by the following parameters:

Temperature range: 45 ° C to +105 ° C (dry bulb)

Relative humidity range: 5% to 90% (noncondensing)

3.1.4Electromagnetic Compliance

The board is designed and implemented so as to minimize electromagnetic emissions, susceptibility, and the effects of electrostatic discharge. The board carries the CE mark, C-Tick mark, FCC

Self Certification logo, Canadian Compliance Statement, and meets the requirements of FCC and CISPR Class B.
