ISL3873
Wireless LAN Integrated Medium Access
Controller with Baseband Processor
The Intersil ISL3873 Wireless LAN
Integrated Medium Access Controller
with Integrated Baseband Processor
is part of the PRISM 2.4GHz radio
chip set. The ISL3873 directly interfaces with the Intersil’s IF
QMODEM (HFA3783). Adding Intersil’s RF/IF Converter
(ISL3685) and Intersil’s Power Amp (HFA3983) offers the
designer a complete end-to-end WLAN Chip Set solution.
Protocol and PHY support are implemented in firmware
thus, supporting customization of the WLAN solution.
Firmware implements the full IEEE 802.11 Wireless LAN
MAC protocol. It supports BSS and IBSS operation under
DCF, and operation under the optional Point Coordination
Function (PCF). Low level protocol functions such as
RTS/CTS generation and acknowledgment, fragmentation
and de-fragmentation, and automatic beacon monitoring are
handled without host intervention. Active scanning is
performed autonomously once initiated by host command.
Host interface command and status handshakes allow
concurrent operations from multi-threaded I/O drivers.
Additional firmware functions specific to access point
applications are also available.
The ISL3873 has on-board A/Ds and D/A for analog I and Q
inputs and outputs, for which the HFA3783 IF QMODEM is
recommended. Differential phase shift keying modulation
schemes DBPSK and DQPSK, with data scrambling
capability, are available along with Complementary Code
Keying to provide a variety of data rates. Both Receive and
Transmit AGC functions with 7-bit AGC control obtain
maximum performance in the analog portions of the
transceiver.
Built-in flexibility allows the ISL3873 to be configured
through a general purpose control bus, for a range of
applications. The ISL3873 is housed in a thin plastic BGA
package suitable for PCMCIA board applications.
The ISL3873 is designed to provide maximum performance
with minimum power consumption. External pin layout is
organized to provide optimal PC board layout to all user
interfaces including PCMCIA and USB.
Ordering Information
