Product name : Chimera
Part Number: SG901-1039

The SG901-1039 is a single chip based 802.11b/g WLAN radio for embedded, low-power and very small form factor mobile applications. The product conforms to the IEEE 802.11b and 802.11g protocols operating in the 2.45GHz ISM frequency band supporting OFDM data rates of 54, 48, 36, 24, 18, 12, 9 and 6Mbps. It also supports CCK data rates of 11 and 5.5Mbps and Legacy data rates of 2 and 1Mbps.

This module has a molex connector for quick installation and field repair.

The SG901-1039 is a fully integrated wireless radio including a ZIF transceiver, RF Synthesizer/VCO, high-speed data converters, an OFDM/CCK digital baseband processor, an ARM9-based MAC and a complete Power Management Unit. The included power amplifier completes a highly integrated chip set solution.

Host control is provided by a flexible serial interface (SPI or SDIO) supporting clock rates of 48MHz.

This complete design allows quick integration into a number of different applications.

The Chimera module is constructed by soldering Diamondback modules to a small carrier board with a connector on the bottom.

SG923-0002 PC-16/SPI Performance Eval Kit

The purpose of this eval kit is to allow instant performance

evaluations. The kit provides an easy way to plug modules into a laptop Cardbus 32 (PCMCIA) interface. The kit includes windows XP drivers. Installation time is very short and immediate performance and software evaluation can begin. We suggest customers begin with this kit and then progress to the software eval kit only when software integration begins.

No software license is required for this kit. The XP driver is provided with the eval board.

This kit is shipped with:
Chimera Wi-Fi module (Diamondback on carrier board)
Extender card
PCMCIA board to SPI interface board
SPI to Wi-Fi inteface board
Instructions
Antenna
CD with drivers for XP
Datasheets for the module and Eval kit

This kit is compatable with the following modules:
Diamondback
Chimera
Coral
Copperhead
Indigo

Eval Kit FAQ.

This kit provides a simple path to install the module in the PCMCIA slot of a common laptop with a windows XP driver. Radio performance evaluations can instantaneously be performed.

While a SDIO connector is available on this kit, it is not recommended for customer use. Only the Cardbus 32 interface is supported by Sagrad at this time.

As it is generally expected, the software integration kit will be better suited for integration with a micro processor eval kit.

SG923-0003 SDIO/SPI Embedded Software Eval Kit.

This kit is expected to be used during Phase 2 of the evaluation where an interested party uses a micro processor evaluation kit combined with this WiFi evaluation kit to complete evaluation of the IC/module with the host processor. This is a very important step and should not be skipped.

This kit includes three interface boards to insure your system will easily integrate with the module.

Licensed software for this Eval kit requires a software license agreement. GPL software is available from this website for development. Mission critical applications should plan to use the licensed software.

SPI

This evaluation kit provides SDIO and SPI interfaces for simple integration into almost any host system. Sagrad encourages the SPI interface for lowest power operation, least amount of software integration and most robust host interface. It is important to remember the host must support a single IRQ as well as a high performance DMA for this to work properly. Many host processors have been integrated with this WiFi technology.

SDIO

STLC 4560 works best at 1.8V on the SDIO interface. This is due to a reliability concern at higher voltages. The part will work fine for many months at 3.3V on the VHIO and tolerate the 3.3V input. However, Sagrad requires a level shifter for any SDIO interface not yet implementing the 1.8V standard interface. Please see our documentation on this topic for more detail.

Please be sure to review the software requirements.

The following items are included in this kit:
CD with datasheets (Software NOT included)
Chimera Wi-Fi module (Diamondback on carrier board)
Antenna
Inter-poser boards (sleep clock, level translation options, power conditioning, connector)
SPI to SPI board
SPI to SPI with level shifting allows 5V operation
SDIO to SPI interface

Software options are available in licensed form for one of the most tested longest existing software stacks in the world. This is provided free of charge but requires a software license agreement.

GPL Software Stack works with these modules.

As it is generally expected, the software integration kit will be better suited for integration with a micro processor evaluation kit.

The general steps for integration are.as follows:

1. Performance evaluation

2. Software integration

3. Hardware integration with Sagrad Module

4. Production in volume

5. Initial evaluation on cost/benefit of integrated solution by customer using IC

6. Production test plan

7. Regulator compliance test plan

8. 802.11 Compliance test plan

9. Production calibration test plan

10. Initial production run and evaluation

11. Production data review

12. Production release
