Description

■ Support for 54, 48, 36, 24, 18, 12, 9, and

The STLC4420A is a single chip dual band WLAN

solution for embedded, low-power, high

performance and very small form factor mobile

applications. The product conforms to the IEEE

802.11b, 802.11g and 802.11a protocols

operating in the 2.4 GHz and 5 GHz frequency

band, supporting OFDM data rates of 54, 48, 36,

24, 18, 12, 9, and 6Mbps in the both bands and

CCK data rates of 11 and 5.5Mbps and legacy

data rates of 2 and 1Mbps at 2.4 GHz.

6Mbps OFDM at 5 GHz

■ Single chip 802.11b/g/a WLAN solution with

fully integrated:

– Zero IF (ZIF) transceiver,

– Voltage controlled oscillator (VCO),

– High-speed A/ D and D/A converters,

– Radio power management unit (PMU),

– OFDM and CCK baseband processor,

– ARM9 media access controller (MAC),

– SPI serial host interface (up to 48Mbps)

– PA bias control

The STLC4420A is a fully integrated wireless

radio including a ZIF transceiver, RF

– Flexible integrated power management unit

– Glueless FEM interface

synthesizer/VCO, high-speed data converters, an

OFDM/CCK digital baseband processor, an

ARM9-based MAC and a complete power

management unit with integrated PA bias control.

An external dual band FEM completes a highly

integrated chip set solution.

■ Intelligent power control, including 802.11

power save mode

■ Fully integrated Bluetooth coexistence

■ Mode selectable SPI or SDIO host interface

(up to 48Mbps)

Host control is provided by a flexible serial

interface (SPI or SDIO) supporting bit rates of

48Mbps. For maximum flexibility, the STLC4420A

accepts system reference clock frequencies of

19.2, 26, 38.4 and 40 MHz. A reference design

evaluation platform of hardware and software is

provided to system integrators to rapidly enable

wireless connectivity to mobile platforms..

Applications

■ Cellular phones

■ Personal digital assistants (PDA)

■ Portable computers

■ Hand-held data transfer devices

■ Cameras
