ISL37300U-EVAL

PRISM 2.5 11Mbps Wireless Local Area

Network miniUSB

The Intersil ISL37300U WLAN miniUSB

(Note 1) is a complete wireless high speed

Network Interface Card (NIC) utilizing the

Intersil PRISM® 2.5 Direct Sequence

Spread Spectrum Wireless Transceiver chip set. It provides a

complete PRISM 2.5 reference design evaluation platform of

hardware and software to system providers or integrators requiring

wireless data communications capability and is ideal for

integration into computer platforms.

Evaluation kits include a WLAN miniUSB designed to Intersil’s

PRISM reference design, Microsoft Windows® Driver, Local Area

Network evaluation software, PRISM Transmitter Test Utilities

(PTTU) software (Note 3) and documentation to get your

evaluation started quickly. Information on the WLAN USB card

may be found in teh ISL37300U-EVAL data sheet. It supports the

IEEE 802.11b network specification for Direct Sequence Spread

Spectrum DSSS signaling, providing data rates of 1, 2, 5.5 and

11Mbps. Access Points are available from a number of suppliers,

enabling a total wireless network solution Typical operating ranges

are shown in Table 1..

FN8022 Functional Overview The WLAN miniUSB is designed to operate in the 2.4GHz ISM frequency band, channels 1 to 11, as specified by the FCC in the USA. The Card will also operate on channels 12 to14, where permitted by local regulatory authorities. Radio equipment must be certified in a country prior to use. Refer to Table 3 for a list of countries and agencies that have approved the ISL37300U-EVAL for operation.
