The following GPIO signal is also available for Wake-on-WLAN functionality:

GPIO 2-11: WOL (Connected to STSCHG on CF interface)

3. Design Overview

The chipset used implements a dual band direct conversion transceiver supporting 2.4GHz band. The chipset uses “Zero Intermediate Frequency (ZIF) architecture for the radio. The architecture contains low-noise amplifiers, quad up/down converters, frequency synthesizers, low-pass filters, baseband AGC receiver amplifiers, transmit/receive switches, and transmitter power amplifiers.

LA-5127 CF card Integration Guide

The 802.11 WLAN MAC protocol is implemented in firmware supporting BSS and IBSS operation. Low-level protocol functions such as request to send (RTS)/clear to send (CTS) generation and acknowledgement, fragmentation and defragmentation, and automatic beacon monitoring are handled without host intervention.

3.1 Transmitter Path

After the Medium Access Controller (MAC) receives the data from the host computer through CF interface, the MAC appends a preamble and header and sends the data to the Base-Band Processor (BBP).

The radio supports the legacy and CCK data rates in 2.4GHz and the OFDM data modulation modes for 2.4GHz band.

The CCK mode transmitter is a Direct Sequence Spread Spectrum (DSSS) PSK modulator when in CCK mode supporting 5.5Mbps and 11Mbps. It also supports DBPSK for 1Mbps and DQPSK for 2Mbps. The preamble is always transmitted as the DBPSK waveform and the header can be configured as DBPSK or DQPSK while the data packets can be DBPSK, DQPSK, or CCK.

The OFDM transmitter supports BPSK, QPSK, 16QAM or 64QAM modulation. The OFDM transmitter operates in 2.4GHz band providing 6, 9, 12, 18, 24, 36, 48, and 54Mbps data rates. The OFDM signal is fed to a pair of Digital to Analog Converters (DACs) to produce the In Phase (I) and the Quadrature (Q) signals. The TX signals are then amplified by the PA and routed through the diplexer to the dual band antenna for transmission.

XXXXXXXX Rev X

3.2 Receive Path

The received signal from the antenna is fed to the diplexer, which separates the signal path for the low band (2.4GHz) and the high band (5.2GHz). The signal is then fed to a filter/balun in the low band and to a balun in the high band path. The signal then goes to the transceiver chip for direct down conversion for both low and high bands. The design contains LNAs, Quad Up/Down Converters, Synthesizers, Low-Pass Filters, and Baseband AGC Receiver Amplifiers.

3.3 Microprocessor Control

LA-5127 CF card Integration Guide

The baseband and MAC chip contains an ARM946E processor core and the SRAM required for implementing the Media Access Control (MAC) functionality. The embedded firmware runs the 802.11 MAC layer control. The MAC control sends and receives packets and transfers data to and from the CF interface to the host computer of the handheld device.

3.4 Frequency Generation

The MAC & Baseband chip has the voltage-controlled oscillator (VCO) required for the design. The VCO operates in one of the two ranges: 9648 to 9936MHz (4X channel frequency for low-band) or 9900 to 11,800MHz (2X channel frequency for high band). The Synthesizer circuit uses the 40MHz crystal oscillator to phase lock the VCO to produce accurate channel frequency for the radio. The frequency range in the low-band is covered in two MHz steps (1MHz at the channel frequency) and in the high-band the LO frequency is covered in five MHz steps (2.5MHz at the channel frequency).

Confidential Material – Disclosure Strictly Prohibited.

7.2 WinCE Card Configuration:

Device configuration is made using a built-in Microsoft OS WLAN configuration service (i.e. a utility) commonly known as Wireless Zero Configuration (WCZ). WZC allows a wireless device to connect to an existing wireless network, change wireless network connection settings, configure a new wireless network connection, and specify preferred wireless networks. WZC will also notify the user when new wireless networks are available. Once a desired wireless network is selected, WZC will automatically configure the wireless card to match the setting of the network and will attempt a network connection.

7.3 WinCE Regulatory Support Software

The WinCE™ 5.0 regulatory support consists of the functionality of the cTxRx (Continuous Transmit and Receive) application that runs on Full Windows. The CEcTxRx communicates with the Symbol transport driver that in turn communicates with the Conexant’s Manufacturing and Test Upper MAC (MTUM) driver to give the application control of the Photon hardware.

The CEcTxRx application provides configuration file based control that sets up the radio to produce continuous transmission of random patterns, continuous transmission of single tone (CW), continuous transmission of predefined packets with a settable interval between the packets, and continuous reception of 802.11 type packets.

Regulatory testing can also be achieved using a remote application for platforms that have small or no displays. This is done using a RAPI connection over the USB. It allows a remote application running on a Windows computer to control the radio in the same way as the CEcTxRx application.

11. Recommended Design Considerations

The following items are recommended for design consideration and integration of

the LA-5127:

1. Design and place the antenna (in the external antenna version) to minimize the coupling back to the radio.

2. Locate the antenna to maintain the VSWR during normal use.

3. Consider human usage factors in placing the antenna/device in the product.

4. Ensure power supply requirements are met and pay special attention to turn-on/turn-off transients.

5. Assure that requirements are met as battery discharges.

6. Assure that radio is not subjected to temperatures exceeding its specifications.

7. Radio temperature specification is based on free air – must be de-rated based on internal temperature rise.

8. Assure that shock, vibration, etc. specifications are not exceeded as mounted.

9. Assure that the mechanical design does not put pressure on the module when mounted.

10. Ensure all operating and environmental conditions are met by design such that the LA5127 is operating within the envelope of its operating environment as specified in paragraph 2.2.3.1 herein.

11. The radiated EVM of the LA-5127 is dependent upon the coaxial cable type, coaxial cable length, and the antenna VSWR. Even though an antenna may meet the 2:1 VSWR specification, care must be taken to select a coaxial cable type and length so that the desired radiated EVM limits are met. Often, the length can be adjusted to optimize the radiated EVM, with changes as small as .25 inch having measurable effects.
