Software described therein, at any time without notice. Motorola makes no commitment to update the Information. 1.2 Background The LA-5137 is the next generation CF client card for embedded solutions and is intended for OEM customers. 1.3 Purpose The purpose of this document is to define the functional characteristics (electrical, mechanical, software interfaces) of the LA-5137 CF Card and provide regulatory information helpful to OEM customers to integrate or embed the CF card in a variety of systems.
1-2 LA-5137 Compact Flash Adapter Integration Guide 1.5 Key Features and Standards The LA-5137 CF Card supports all required modes of operation as an 802.11a/b/g Mobile Unit (MU). In 802.11g mode, the radio supports three different modulation modes: Legacy 1 and 2 Mbps, Complimentary Code Keying (CCK), and Orthogonal Frequency Division Multiplexing (OFDM).
• Mobile workers in health care, education, retail, manufacturing, hospitality and other industries with 802.11a, 802.11b, and 802.11g wireless LAN access. • Corporate Motorola device users with Wi-Fi wireless LAN access at the office, or with a subscription to a public wireless LAN.
2.1 System Architecture The LA-5137 is a modified type 1 CFA card. The LA-5137 Compact Flash Adapter CF card consists of all of the integrated circuits necessary to provide WLAN transceiver functionality for the 2.4GHz and 5 GHz bands. The Wireless LAN integrated Media Access Controller with Baseband processor directly interfaces with the Dual Band Direct Conversion transceiver.
2.2 Hardware Environment 2.2.1 Introduction The LA-5137 CF card can be used in handheld mobile devices to provide wireless network access. It communicates using Radio Frequencies (RF) between two or more users or between a user and the wired network. The module implements the IEEE 802.11a/g physical (RF) specification. The chipset used provides for modulation, demodulation, spreading, and despreading of the RF signals.
Please check the appropriate regulatory authority or contact Motorola for more information. 2.2.6 TX and RX Diversity TX and RX diversity is only supported on the connector version of LA-5137 (LA-5137-1002-WWR). 2.2.7 Operating Channels Channel...

Table 2.2 IEEE 802.11a Channels 2.2.8 Electrical Interface The electrical interface for LA-5137 is PC16. The chipset used supports this interface; therefore no external component is required. The host must support the PC16 interface as well. This card only uses 16-bit interface.
Design Overview The chipset used implements a dual band direct conversion transceiver supporting 2.4 GHz and 5 GHz bands. 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.
3-2 LA-5137 Compact Flash Adapter Integration Guide 3.3 Microprocessor Control 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.
Unless otherwise stated the following specifications hold over 0C to +55C, and 3.3V +/- 5%. NOTE: This environment is defined as the specific temperature envelop containing the LA-5137 radio product. If embedded within a host product, this envelop is the internal ambient temperature of the host under the host’s operating conditions.
