Applications

The CW1260 is an IEEE 802.11a/b/g/n WLAN single-chip solution and is fully optimized for a wide-variety of applications such as mobile phones, tablets, wireless home audio entertainment systems, portable media players and gaming consoles.

Extremely low power consumption and intelligent host offloading of network stack functions, roaming and packet processing ensures industry-leading battery life. High levels of integration allow for very compact and cost-effective reference designs providing fast time to market for new WLAN-enabled products.

Building on its successful predecessors, such as the CW1200 and CW1250, the CW1260 integrates a power amplifier with higher Tx output power and reduced power consumption, a switch-mode power supply and an enhanced Bluetooth coexistence interface.

Being an ideal partner to ST-Ericsson’s CG2905 GNSS/Bluetooth/FM, the CW1260 uses simultaneous receive and enhanced Bluetooth/WLAN coexistence to provide superior performance and flexibility to single-chip Bluetooth/WLAN solutions.

The CW1260 also offers standard PTA supporting a wide range of Bluetooth or WiMAX solutions. The integrated SMPS can support GNSS, Bluetooth, FM and other connectivity devices reducing overall BOM costs.

A comprehensive suite of software is provided, including proven drivers for Android/Linux, RTOS and Windows based platforms, along with production test and engineering software utilities.
