Applications

Description

The STLC4560 is a single chip 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 2.45 GHz ISM

frequency band supporting OFDM data rates of

54, 48, 36, 24, 18, 12, 9, and 6 Mbit/s as well as

CCK data rates of 11 and 5.5 Mbit/s and legacy

data rates of 2 and 1 Mbit/s.

The STLC4560 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

with integrated PA bias control. In addition some

passive components are integrated further

reducing the overall reference design cost and

size. An external FEM completes a highly

integrated chip set solution.

Host control is provided by a flexible SPI or SDIO

serial interface. The SPI interface supports a

maximum clock rate of 48 MHz whereas the 4-bit

SDIO supports a maximum clock rate of 25 MHz.

For maximum flexibility, the STLC4560 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.
