THIS LISTING IS FOR (100 PCS) OF ISL3872IK18 BY INTERSIL
WIRELESS LAN INTERGRATED MEDIUM ACCESS CONTROLLER WITH BASEBAND PORCESSOR
WIRELESS LAN INTERGRATED MEDIUM ACCESS CONTROLLER WITH BASEBAND PORCESSOR
The Intersil ISL3872 Wireless LAN
Integrated Medium Access Controller
with Integrated Baseband Processor
is part of the PRISM® III, 2.4GHz
radio chipset. The ISL3872 directly interfaces with the
Intersil’s RF Front End (
ISL3684). Adding Intersil’s Power Amp
(ISL3984) offers the designer a complete end-to-end WLAN
Chipset solution.
Protocol and PHY support are implemented
in firmware thus, allowing 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.
The ISL3872 has on-board A/D and D/A converters for
analog I and Q inputs and outputs, for which the ISL3684
Zero-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 ISL3872 to be configured
through a general purpose control bus, for a range of
applications.
The ISL3872 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 mini PCI.
The ISL3872 is housed in a thin plastic BGA package
suitable for mini PCI board applications
