The Digi Connect Wi-Wave module is an 802.11b/g WLAN communications module

for use in embedded applications. The module is a single circuit card packaged in a
PCI Express Mini Card form factor, and supports all the RF, analog, and digital
circuitry necessary to implement WLAN functionality. Using Digi’s baseband
processor technology, this module is the ideal choice for embedded applications
requiring long-term product availability in conjunction with reliability and easy
design integration.

The primary interface to the module is through a standards-compliant PCI Express
Mini Card edge connector, using a USB 2.0 full speed/high speed link for
communication with the host system.

Features

Note:

The Connect Wi-Wave module also provides a dual diversity antenna option through
two on-board U.FL connectors, which allow for cabling to remote 2.4 GHz antennas.

 Ultra-compact and standards-based form factor

 Easy design integration through USB 2.0 full speed/high speed interface

 Dual diversity antenna option through two on-module U.FL antenna connectors

 Digi 802.11b/g baseband processor technology for long-term product

 -30°C to +70°C operating temperature for harsh environments

 RoHS compliant design

The Connect Wi-Wave edge connector pinout is compliant with the PCI
Express Mini Card Electromechanical Specification, Revision 1.1 (March 28,

2005) with this exception: the Connect Wi-Wave has a 4-wire JTAG
programming interface mapped to pins 45, 47, 49, and 51.

The Connect Wi-Wave module edge connector is a 52-pin connector whose pinout
follows the standard PCI Express Mini Card edge connector pinout as stated in the
PCI Express Mini Card Electromechanical Specification, Revision 1.1, with this
exception: JTAG signals are mapped onto pins 45, 47, 49, and 51. These signals are

U.FL connectors The module uses two U.FL antenna connectors (P1 and P2) to allow for cabling to

embedded antennas or external antenna connectors. For more information, see
Chapter 3, “Using the Antenna.”

USB peripheral controller

The module uses a peripheral USB controller to interface to either a full speed or
high speed USB 2.0 link. The link first tries to communicate to the host system
board at the high speed USB rate (480 Mbps). If not successful, the link reverts to
the full speed USB rate (12 Mbps). This link is used for all communication between
the module and the host system board.

802.11b/g modes and channels

The Connect Wi-Wave transmits and receives data at up to 11 Mbps when operating
in 802.11b mode and up to 54 Mbps when operating in 802.11g mode. It supports
these 802.11b/g channels:

 Channels 1 through 11 for North America (2.401 GHz–2.473 GHz)

Voltage regulators

The module takes in 3.3V±9% (3.00V to 3.60V) as its main input power. This power is
filtered and used as a 3.3V supply to portions of the digital logic. This power also
acts as input to dedicated on-board voltage regulators.

The module does not provide a voltage monitor or automatic reset signal generator;
rather, the module uses a reset signal generated by the host system board.

LEDS

The module does not have any on-board LEDs, but it drives the LED_WLAN# signal
(pin 44) to indicate WLAN association and transmit/receive activity. This table
shows the different LED states:

LED state Indication

Off Not powered on

On Associated and authenticated

Slow blink Not associated or authenticated

Voltage monitor — Reset generator

. . . . .

Intermittent blink Transmit/receive activity

Power

The module requires only +3.3 VDC, 750 mA max. This power must be a well­regulated +3.3V supply due to limited supply filtering in the module. The digital
inputs and outputs are 3.3V CMOS compatible. See “Power requirements” on
page 38 for specifications.

DISABLE signal The module supports the active low

Express Mini Card Electromechanical Specification. This signal not only disables the
power supplies to the radio portion of the module, it also powers down additional
portions of the module to reduce power consumption to a minimum.
