When IEEE802.11b functionality is all that an application requires, Texas Instruments’ ACX100 delivers a field-tested, single-chip wireless LAN medium access controller (MAC) integrated with a Wi-Fi®-compliant (802.11b) spread spectrum baseband processor.
The ACX100 interfaces directly to a host and a radio to provide a complete solution for OEM and ODM design teams who need to turn out system-level designs quickly.
Applications
- CardBus/PCI/mini-PCI WLAN adapters
- High-speed WLAN access points
- High-speed WLAN bridges
- 2.4-GHz WLAN systems
- Portable notebook/PDA computer links
- Part 15-compliant radio links
- Portable bar code scanners/POS terminals.
Key Features
- Data rates: 1, 2, 5.5, 11, and 22 Mbit/s
- Embedded ARM® 7TDMI CPU and RAM
- Supports all IEEE 802.11b modulations
- Supports multiple radio topologies
- Targets Wi-Fi systems compliance
- Processing gain up to 15 dB
- Multipath delay spread tolerance > 250 ns
- Supports JTAG boundary scan
TI’s ACX100 delivers the most aggressive data rates available in the 2.4 GHz WLAN market. By employing advanced forward error correction (FEC) and modulation techniques, the ACX100 achieves much higher performance than its competitors. ACX100’s proprietary application of Packet Binary Convolutional Code (PBCC™) technology provides data rates up to 22 Mbit/s in 8.5 dB of signal-to-noise response (SNR) with a packet error rate (PER) of 10 -2.
