Wireless LAN Integrated Medium Access

Controller with Baseband Processor

interfaces with the Intersil’s ISL3690 Dual Band Direct

Conversion transceiver. Adding Intersil’s ISL3090 10GHz VCO

and Intersil’s ISL3990 Dual Band Power Amp completes an end-

to-end WLAN Chipset solution providing both 5 GHz 802.11a

and 2.4GHz 802.11b/g access point capability. The 802.11

protocol is implemented in firmware to allow custom WLAN

solutions.

Firmware implements the full IEEE 802.11 Wireless LAN

MAC protocol. It supports BSS under Distributed

Coordination Function (DCF). This allows the ISL3893 to

serve as a self hosted Access Point.

Orthogonal Frequency Division Multiplexing (OFDM)

modulated with BPSK, QPSK, 16QAM, or 64QAM and a

variety of convolutional coding rates provides 8 selectable

data rates at 2.4GHz and 5GHz. Differential phase shift

keying modulation schemes, DBPSK and DQPSK with data

scrambling capability along with Complementary Code

Keying provide 4 additional selectable data rates at 2.4GHz.

Built-in flexibility allows the ISL3893 to be configured for a

range of applications. The MAC is based on the ARM 946E

processor core that offers a wide variety of code

development support tools.

The ISL3893 is housed in a thin plastic BGA package.
